dna 2
The "thread of life", is deoxyribonucleic acid, otherwise known as DNA. It is the spiral shaped molecule found in the nucleus of cells. Scientists have known since 1952 that DNA is the basic substance of heredity. This was hypothesized, and later confirmed by James D. Watson and Francis Crick. They also know that it acts like a biological computer program over 3 billion bits long that "spells" out instructions for making the basic building blocks of life.DNA carries the bodies genetic code, controls the development of an embryo, is capable of duplicating itself, and is able to repair damage to itself. DNA can be manipulated to change all kinds of things. All DNA molecules consist of a linked series of unites called nucleotides. Each DNA nucleotide is composed of 3 subunits: a 5 carbon sugar called deoxyribose, a phosphate group that is joined to one end of the sugar molecule, and one of several different nitrogenous bases li
Many questions have been raised by a number of people and scientists about the ethics of DNA research. It was once feared that the insertion of a disease causing substance could cause a deadly epidemic in the general population upon accidental release. But, since 1973 when they first used the technique it has been transferred thousands of times without any of the feared catastrophes occurring. But, still there are many questions remaining to be answered. Is it right for people to change their babies' eye color, or any other aspect of their baby? Should employers be allowed to see your DNA, to see if you are at risk for a certain disease? nked to the opposite end of the deoxyribose. There are 4 nitrogen bases called adenine, guanine, thymine, and cytosine. In DNA adenine pairs with thymine and guanine with cytosine. Medicine's ability to diagnose continues to exceed its ability to treat or cure. For example, Huntington's Chorea is an inherited disease that develops between the ages
