Definition of DNA ( Deoxyribo Nucleic Acid)
DNA, which stands for DeoxyriboNucleic Acid is an EXTREMELY (by cellular standards) long macromolecule which forms the main component of chromosones (a basic component in the genetic determination and development of all known life forms).
DNA, structurally, is composed of two nucleotide 'strands', which coil around each other like a set of spiraling stair cases. It is constructed of two main chains of alternating phosphate and deoxyribose units, bound together chemically with purine and pyrimidine bases (known as adenine, guanine, cytosine and thymine)
DNA is a chemical polymer and is found in the nucleus of the cell. The specific ordering of the chemical bases (mentioned earlier) found within DNA allow it to store and maintain the biological characteristics of all living things. The Laws by which the DNA sequences govern our biological traits are known as the laws of genetics.
DNA is physically capable of self replicating, as well as chemically capable of synthesizing the creation of RNA, a cellular messenger which distributes genetic and cellular information within the cells. This distribution of information facilitates protein synthesis as well as the functionality of genetic determination.

Description : The work of geneticists who have labored for years to map human DNA is the subject of this offbeat yet highly informative documentary from the PBS series Nova. Host Robert Krulwich, a correspondent for ABC Nightline, visits with scientists who explain, in terms understandable to laymen, the enormous challenges faced and overcome by scientists working on the Human Genome Project.

Description : What makes DNA different from hordes of competitors purporting to help readers understand genetics is that it is written by none other than James Watson, of Watson and Crick fame. He and his co-author Andrew Berry have produced a clear and easygoing history of genetics, from Mendel through genome sequencing. Watson offers readers a sense of immediacy, a behind-the scenes familiarity with some of the most exciting developments in modern science.
