deoxyribonucleic acidThere is no substance as important as desoxyribonucleic acid, Watson, 1991. element therapy is a controversial issue in todays wisdom society. Debates in the United States are covering a wide track down of topics. I will discuss just a few viewpoints from both sides.First of all, a little background on desoxyribonucleic acid and communicables. DNA, or deoxyribonucleic acid, is a complex structure consisting of a double stranded gyre made up of complementary grip pairs. Adenine (A) pairs up with tetraiodothyronine (T) and guanine (G) matches with cytosine (C). They are held together with the help of hydrogen bonds. The roll is spiral shaped, and the outside of DNA is alternating sugar and phosphate groups. Watson and crick presented this structure in 1953. The factortic code is imprinted in the precise installment of the nitrogenous bases running down the length of DNA molecule. Lee, 1993. A base triplet code is made up of tercet nucleotides. Each DNA t riplet code is translated via a messenger RNA into a protein. DNA has a semiconservative replication process where the double strands unwind and serve as templates.A genome is a collection of DNA molecules that make up am organism. There is great diversity betwixt different species and even between the same species. The human genome contains up to three billion base pairs, the genetic difference among individual humans is as much as three million base pairs of DNA (Davis, 1990).A genetic mutation is where a gene is diverged to another form. A mutation does not imply a detrimental thing happened. They can be deleterious, cause disease, reduce fitness or even be lethal. A mutation can also be beneficial if it increases adaptability or advantages in a species. Or a mutation can be silent and cause no apparent change in the organism. T... ...ecoming a safer, more efficient process that may or so day cure the world of all genetic disease. Some day, beingness sick may just mean get ting gene therapy.BibliographyJoel Davis, use the Code The Human Genome Project and the Choices of Modern Science, John Wiley & Sons, Inc., 1990.Thomas F.
