Wilmut And Dr Unicellular Organisms
1,428 wordsThe biological definition of a clone is an organism that has the same genetic information as another organism or organisms ("Cloning", 1997). From this definition and from information about the science behind cloning, my current view on cloning is that it is ethical. This statement ignores information about how we can misuse cloning and what consequences occur when the procedure is unsuccessful. I currently do not think cloning should be used until it is perfected. I doubt however that we will a...

Cd 4 Cells Reverse Transcriptase
1,846 wordsThe content of this paper is whether or not mutations undergone by the Human Immunodeficiency Virus and allow it to survive in the immune system. The cost of treating all persons with AIDS in 1993 in the United States was $ 7. 8 billion, and it is estimated that 20, 000 new cases of AIDS are reported every 3 months to the CDC. The question dealing with how HIV survives in the immune system is important, not only in the search for a cure for the virus and its inescapable syndrome, AIDS (Acquired ...

Adult Dna Cloning Human Cloning Technology
1,788 wordsThe possibility of human cloning was raised when Scottish scientists, led by Dr. Ian Wilmut at the Roslin Institute, created the much-celebrated sheep "Dolly." Being the first mammal ever cloned this aroused worldwide interest and concern because of its scientific and ethical implications. The feat, cited by Science Magazine as the breakthrough of 1997, also generated uncertainty over the meaning of "cloning" -- an umbrella term traditionally used by scientists to describe different processes fo...

Extra Chromosome Genetic Material
1,960 wordsIn 1942, Dr. Harry Klinefelter and his coworkers at the Massachusetts General Hospital in Boston published a report about nine men who had enlarged breasts, sparse facial and body hair, small testes, and an inability to produce sperm. By the late 1950 s, researchers discovered that men with Klinefelter syndrome, as this group of symptoms came to be called, had an extra sex chromosome, XXY instead of the usual male arrangement, XY. In the early 1970 s, researchers around the world sought to ident...

Type Of Cloning Desirable Traits
1,048 wordsGenetic engineering is the changing of an organism's DNA, genetic material to eliminate unwanted traits or to produce desirable traits. The earliest form of genetic engineering dates back to the scientist Gregor Mendel who did experiments with peas. He bred only the peas with the most desirable traits in order to achieve a healthier and stronger pea (McCuen 8). This method, called selective breeding, is still used today with plants and animals in order to increase food production. Corn plants ar...

Nucleic Acid Base Pairs
536 wordsThe article, "Structure for Deoxyribose Nucleic Acid", written by Watson and Crick, was a stepping stone on the path of discovery for the building blocks of life. In this article, Watson and Crick briefly state previous theories on the structure of DNA were incorrect in certain aspects but correct in others. Watson and Crick later went on to describe their version of a double helical structured DNA. They indirectly state the importance of their discovery which later them to winning the noble pri...

Adult Dna Cloning Felt That Cloning
2,659 wordsHow much longer until the designer baby is born? Not so long ago cloning of a human was merely a science fiction. As for me, not so long ago Ive read a book (science fiction), which described the lives of people in future, somewhere in 2240. This book described a human race as a race in which children are modified before their birth according to the tastes of their parents. Author pointed that such modification was not always good for a child. As for me, it was rather creepy to read. More than t...

Cloning Of Humans Type Of Cloning
1,364 wordsCloning The concept of cloning, introduced by scientists and adopted by modern popular vocabulary, is one of the most emotional and controversial issues. Cloning became a subject of worldwide public interest and discussions in 1997, when scientists of Roslin University produced and demonstrated Dolly the cloned sheep, though the history of cloning experiments and tests on reproductive techniques goes back for more than a century. Cloning used to be an item of usual terminology of scientists, def...

Type Of Cloning Cloning Of Humans
1,762 wordsCloning Cloning as a concept has been recently launched by scientists and adopted by contemporary popular language. In 1997 biologists together with genetic and medical specialists of Roslin University in Scotland managed to produce the cloned sheep Dolly and officially publicized its existence. [ 2 ] Since those times the idea of cloning became a subject of intense interest and permanent discussions all around the world. For the last decade it remains to be one of the most emotional and controv...

Wilmut And Dr Unicellular Organisms
2,092 wordsThe biological definition of a clone is an organism that has the same genetic information as another organism or organisms. Thus, an elaboration on the history, techniques, ethics, and reasons for researching the technology of cloning is necessary. A clone is an organism derived asexually from a single individual by cuttings, bulbs, tubers, fission, or parthenogenesis reproduction. Parthenogenesis reproduction is the development of an organism from an unfertilized ovum, seed or spore. Hence, clo...

Cystic Fibrosis Enucleated Egg
2,092 wordsThe first thing that must be cleared up is what is cloning, and what is a clone. A clone is an organism derived asexually from a single individual by cutting, bulbs, tubers, fission or parthenogenesis reproduction. Parthenogenesis reproduction is the development of an organism from an unfertilized ovum, seed or a spore. Hence, cloning, biologically speaking, is any process in which production of a clone is successful. Thus, the biological term cloning is the production of genetically identical d...

O J Simpson Cloning Of Humans
3,365 wordsDNA Deoxyribonucleic Acid the material that codes for amino acids which form proteins, which in turn carry out functions of the cell. DNA is responsible for building life. Our physical characteristics, susceptibility to some diseases and disorders (e. g. breast cancer, sickle cell anemia), and a few behavior characteristics are passed from generation to generation through DNA. DNA controls everything about the way we look, from the color of the eyes to how tall you are to the width of your feet....

Nitrogenous Bases Amino Acids
1,451 wordsDeoxyribonucleic acid and DNA DNA Deoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20 th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. (Miller, 139) DNA is the genet...

Sickle Cell Trait Genetic Variation
1,141 wordsGenetic variation and environmental variation play a key role in the process of evolution. Genetic variation refers to the differences between individuals that are caused by the genes they inherited from their parents. Genetic variation takes place on three different levels. First it takes place in the DNA through random mutations. Secondly, genetic variation occurs at the level of the organism by meiosis and fertilization. Thirdly, genetic variation takes place at the level of a whole populatio...
