The Human Genome Project Essays (952 words) - Biology, Genetics

The Human Genome Project The Human Genome Project is a worldwide research effort with the goal of analyzing the structure of human DNA and determining the location of the estimated 100,000 human genes. The DNA of a set of model organisms will be studied to provide the information necessary for understanding the functioning of the human genome. The information gathered by the human genome project is expected to be the source book for biomedical science in the twenty-first century and will be of great value to the field of medicine. The project will help us to understand and eventually treat more than 4,000 genetic diseases that affect mankind. The scientific products of the human genome project will include a resource of genomic maps and DNA sequence information that will provide detailed information about the structure, organization, and characteristics of human DNA, information that constitutes the basic set of inherited "instructions" for the development and functioning of a human being. The Human Genome Project began in the mid 1980's and was widely examined within the scientific community and public press through the last half of that decade. In the United States, the Department of Energy (DOE) initially, and the National Institutes of Health (NIH) soon after, were the main research agencies within the US government responsible for developing and planning the project. By 1988, the two agencies were working together, an association that was formalized by the signing of a Memorandum of Understanding to "coordinate research and technical activities related to the human genome". The National Center for Human Genome Research (NCHGR) was established in 1989 to head the human genome project for the NIH. NCHGR is one of twenty-four institutes, centers, or divisions that make up the NIH, the federal government's main agency for the support of biomedical research. At least sixteen countries have established Human Genome Projects. The Office of Technology Assessment (OTA) and the National Research Council (NRC) prepared a report describing the plans for the US human genome project and is updated as further advances in the underlying technology occur. To achieve the scientific goals, which together encompass the human genome project, a number of administrative measures have been put in place. In addition, a newsletter, an electronic bulletin board, a comprehensive administrative data base, and other communications tools are being set up to facilitate communication and tracking of progress. The overall budget needs for the effort are expected to be about $200 million per year for approximately 15 years. Lasers are used in the detection of DNA in many aspects of the project; a very important use is in sorting chromosomes by flow cytometry. Lasers are also used in confocal fluorescence laser microscopy to excite fluorescently tagged molecules in genome mapping, in addition to other mapping uses. In diagnostic applications, lasers are used with fluorescent probes attached to DNA to light up chromosomes and to create patterns on DNA chips. From the beginning of the human genome project it was clearly recognized that acquisition and use of such genetic knowledge would have momentous involvements for both individuals and society and would pose a number of consequential choices for public and professional deliberation. As Thomas Lee writes, "the effort underway is unlike anything ever before attempted, if successful, it could lead to our ultimate control of human disease, aging, and death". Whatever its justification, the human genome project has already inspired society with the hope of "better" babies, and one way to deploy pragmatism in the analysis of genetic engineering is to look at this promise of "better" babies in its social context: parenthood. Parents hope for healthy children and, if they could afford it, make choices (such as choosing parental care) to help "engineer" healthier babies. Genetic engineering seems in this respect to offer the brightest hope for parents. Through germ-line therapy, disastrous, but genetically discrete diseases, such as Huntington's and cystic fibrosis could be removed from the DNA of the egg or zygote. Clearly parents would follow the model in choosing to avoid a short, painful life for their children. Another more reasonable fear is that we have not the slightest idea what we are doing and ought to avoid making hasty choices. Hybrid varieties are often

Excerpt From Life on the Mississippi by Mark Twain

Excerpt From Life on the Mississippi by Mark Twain In this excerpt from his autobiographical book Life on the Mississippi, written in 1883, American novelist, journalist, lecturer and humorist Mark Twain considers what may be lost as well as gained through knowledge and experience. The passage below, Two Ways of Seeing a River, is Twains account of learning to be a pilot of a steamboat on the Mississippi River in his earlier years. It delves into the changes in attitude about the river he experienced after becoming a steamboat pilot. In essence, it reveals the reality versus the myth of the majestic, Mighty Mississippirevealing danger beneath the mesmerizing beauty that could only be discovered by taking to the river itself. Two Ways of Seeing a River by Mark Twain Now when I had mastered the language of this water and had come to know every trifling feature that bordered the great river as familiarly as I knew the letters of the alphabet, I had made a valuable acquisition. But I had lost something, too. I had lost something which could never be restored to me while I lived. All the grace, the beauty, the poetry had gone out of the majestic river! I still keep in mind a certain wonderful sunset which I witnessed when steamboating was new to me. A broad expanse of the river was turned to blood; in the middle distance the red hue brightened into gold, through which a solitary log came floating, black and conspicuous; in one place a long, slanting mark lay sparkling upon the water; in another the surface was broken by boiling, tumbling rings, that were as many-tinted as an opal; where the ruddy flush was faintest, was a smooth spot that was covered with graceful circles and radiating lines, ever so delicately traced; the shore on our left was dens ely wooded, and the sombre shadow that fell from this forest was broken in one place by a long, ruffled trail that shone like silver; and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed splendor that was flowing from the sun. There were graceful curves, reflected images, woody heights, soft distances; and over the whole scene, far and near, the dissolving lights drifted steadily, enriching it, every passing moment, with new marvels of coloring. I stood like one bewitched. I drank it in, in a speechless rapture. The world was new to me, and I had never seen anything like this at home. But as I have said, a day came when I began to cease from noting the glories and the charms which the moon and the sun and the twilight wrought upon the rivers face; another day came when I ceased altogether to note them. Then, if that sunset scene had been repeated, I should have looked upon it without rapture, and should have commented upon it, inwardly, in this fashion: This sun means that we are going to have wind to-morrow; that floating log means that the river is rising, small thanks to it; that slanting mark on the water refers to a bluff reef which is going to kill somebodys steamboat one of these nights, if it keeps on stretching out like that; those tumbling boils show a dissolving bar and a changing channel there; the lines and circles in the slick water over yonder are a warning that that troublesome place is shoaling up dangerousl y; that silver streak in the shadow of the forest is the break from a new snag, and he has located himself in the very best place he could have found to fish for steamboats; that tall dead tree, with a single living branch, is not going to last long, and then how is a body ever going to get through this blind place at night without the friendly old landmark? No, the romance and the beauty were all gone from the river. All the value any feature of it had for me now was the amount of usefulness it could furnish toward compassing the safe piloting of a steamboat. Since those days, I have pitied doctors from my heart. What does the lovely flush in a beautys cheek mean to a doctor but a break that ripples above some deadly disease? Are not all her visible charms sown thick with what are to him the signs and symbols of hidden decay? Does he ever see her beauty at all, or doesnt he simply view her professionally, and comment upon her unwholesome condition all to himself? And doesnt he sometimes wonder whether he has gained most or lost most by learning his trade?

Creation Myths Essay Example | Topics and Well Written Essays - 750 words

Creation Myths - Essay Example One of the common elements is the presence of a god or gods that brought about the creation of the elements of the sky and the earth and the first humans. This provides insight to the beliefs of people in ancient times that no physical environment or beings came from nothing. They were created by a supreme being in the same way that people create things from the materials present in the environment. In so many ways, the myths are a representation of the story of beginnings and creations in the human setting. For instance, the three creation myths include a theme of birth. In the Egyptian creation myth, "Ra (the sun) came out of an egg that appeared on the surface of the water" (Aldokkan). Ra also gave birth to other gods. In the Greek myth, Chaos, the void that encompasses the entire universe, gave birth to Gaia, called Earth, and Uranus, the sky (Elliot). The Enuma Elish tells of the union of Apsu (fresh water) and Tiamat (salt water) giving birth to gods. The first part of the first tablet talks of "their waters commingling as a single body" ("The Enuma Elish"). Another similarity among the three myths is the allusion to water and chaos when there was nothing yet that existed. In the Egyptian myth, this is represented by Nu, the watery chaos. In the Enuma Elish, everything began with Apsu and Tiamat, who represent the waters. In the Greek story, an unending stream of water, dominated by the god Oceanus, surrounded Chaos. The use of the water theme should not be surprising, as it would have been very much influenced by the fact that in the past, a large part of the earth was covered by huge amounts of water. There were also many tales of floods and inundation in ancient times, pointing to how the physical environment would have been like during those times. All of the creation myths also contain the themes of wars, revenge, and quest for power among gods that eventually led to the creation of various parts of the universe. With the creation myths, the gods possess immense powers that brought them in conflict with other gods. In all the myths, there is also the common theme wherein a sole supreme being emerges through all the chaos. In the Greek myth, this is represented by Zeus, who triumphed over his father, Cronus. This victorious being in the Babylonian myth is Marduk, who defeats Tiamat, splits her body into two to form the heaven and the earth ("The Enuma Elish"). The Egyptian myth has two versions, but in those two versions, it was either Osiris or Horus, the son of Isis and Osiris in one version, that emerged as the supreme being. In all the depictions of the behaviors and actions of the gods, one can see how much people in the past were amazed and acted under the mercy of the gods. Most of the ancient beliefs and religions attribute godlike attributes to elements and forces of nature. Nature is the one uncontrollable force for man that he believed that their outbursts manifested by earthquakes, strong storms, or volcanic eruptions, must have been due to the anger and temper of the gods, or the mischief of man. In any case, man is dependent on the gods of nature, who may wage war against other gods with little or no thought of the creatures, including men, on earth. Man is dependent on nature to grow his crops and produce food, and he would have to rely on faith in

The economics of Exhaustible Resources Essay Example | Topics and Well Written Essays - 3500 words

The economics of Exhaustible Resources - Essay Example This essay discusses that without a doubt, economists’ description of exhaustible resources is based on the prediction of production and price trajectories and the likelihood of resources exhaustion. This is because; exhaustible resources have limited life span considering the optimal exploitation of resources at the both individual and industrial level. As a result, focus on Harold Hotelling explanation on maintenance of exhaustible resources is based on the importance of sustainability of a production–consumption system as a way of controlling extinction of exhaustible natural resource without getting comparative advantage from it as compared to its future demand. More significantly, it is imperative for exploitation of non-renewable resource to be undertaken for the benefit of the people and a country’s economy considering the level of extinction and financial value derived. Considerably, it is essential to make decisions considering the economic models that f ocus on sustainable economic growth taking into account resource constraints. As a result, it is decisive to evaluate on whether or not it is viable to carry out exploration on the extent in which resource constraints can be overcome by substitution and technological change. Nonetheless, the influence of the extinction of natural non-renewable resources is focused on the current initial stock of the resource considering the amount of the resource to be extracted within different periods with the main aim being on the maximization of profits. (Hotelling 139). However, it is difficult for a country to avoid exploiting its exhaustible resources especially when there is a high demand for the commodity. More so, it is essential to consider that non-renewable resources provide a comparative advantage because countries could be the sole producers of valuable non-renewable resources. As a result, such country’s take advantage of their monopolistic position in the resource market, as it lacks competition in the production of the exhaustible resources thus, positioning itself strategically in the world market (Martinet 17). In addition, a country makes a decision on price that the exhaustible resource would be sold as it gains competitive advantage, when negotiating for the prices being the sole producers of such extinct natural resources like oil. Thus, the duty of a government is to create ways in which the non-renewable resources can be sold in the world market resulting in a country getting a chance to exploit the non-renewable resources it has by using the best-suited strategies of price maximization. Although, exhaustible resources bring international trading to a country it also creates issues in terms of international development in the world. More so, exhaustible resources are predicted by production and price trajectories thus it becomes difficult for countries to make viable decisions considering the fact that the resources become scarce leading to inc rease in prices of non-renewable resources. However, such decisions of taking advantage of the prevailing high prices does not take into consideration the international development issues including effects resulting from the extinction of most of the natural resources that are in the risk of extinction because they are non-renewable (Solow & Wan 360). More significantly, the dominance in the monopolistic market of different natural resources have seen organizations that are establish by countries join to create a common stand in the provision of higher prices of the exhaustible resource they produce. For example, oil producing and exporting countries (OPEC) that deals with the oil
