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

Even with the best tools of today, the progress is full of surprises. Human DNA is not like that of plants, in which the trait of color of a flower is determined by one gene. Even the color of a human eye can involve the interaction of several genes. Some complex genes, such as cystic fibrosis, can go wrong in any number of places. Scientists have already accounted for 350 places where the cystic fibrosis gene mutates, and more are being uncovered weekly.

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 of 30 and 45, can be diagnosed before any symptoms appear. This can be hard for both the individuals with the disease and their family.

Many questions have been raised by a number of
