The Science and the Laws Impacting Human Cloning Essay

The Science and the Laws Impacting Human Cloning Human cloning, long the subject of science fiction, is today a practical reality. Recent breakthroughs, most renowned the cloning of a sheep from an adult cell in Scotland in 1997, have caused the world to acknowledge that human cloning is indeed possible. Governments around the world immediately attempted to address the issue of human cloning, with varying levels of success. At the same time the pace of cloning technology continued to accelerate. This paper will first examine the development of the technology that makes human cloning possible and the scientific uncertainties surrounding it. While this paper does not intend to take a stand on either side of†¦show more content†¦In complex organisms, cells undergo a process of differentiation where genes not necessary for the functioning of a particular cell are turned off. The unique differentiated state of a cell depends on its particular combination of regulatory proteins2. While cells may differentiate to perform a number of different functions, each cell still contains the entire DNA sequence necessary to become any kind of cell. The general consensus was that all embryo cells hold the potential to become any type of cell, but older fetal and adult cells could only express the genes that have already been turned on3. Until recently many scientists believed that once a cell differentiates, it is forever specialized Based on this preceding assumption, previous cloning research, which dates as far back as 1890, focused on splitting the embryos of animals at early stages of development to produce identical organisms4. As early as 1952, scientists were able to clone many species of animals through a process of nuclear transfer of embryonic nuclei. This process was only limited to producing identical versions of organism in the embryonic stage, however. Scientists could produce a series of identical clones at the time of fertilization, but could not actually clone an adult organism, which is the reason cloning is desirable in the first place and so very controversial.

Oh we would say that perhaps at some point in the distant future, cloning might become feasible through the use of sophisticated biotec hnologies far beyond those available to us now. But what we really believed, deep in our hearts, was that this one biological feat we could never master. Dr. Lee M. Silver, 1997.

Biotechnology has been used by humans to produce staple foods since the beginning of civilisation. The domestication of plants and animals and the use of microorganisms to make cheese, yoghurt, bread, beer and wine are examples of early uses of biotechnology. Modern biotechnology involves understanding genes andRead MoreTechnology Essay11684 Words   |  47 Pagesthat contribution technology has made to modern life has been really positive and has helped to improve the quality of human lives.
