DNA

DNA, or Deoxyribonucleic Acid, is described, in Encarta Encyclopedia as a genetic material of all cellular organisms and most viruses. DNA carries the information needed to direct protein synthesis and replication. Protein synthesis is the production of the proteins needed by the cell or virus for its activities and development. Replication is the process by which DNA copies itself for each descendant cell or virus, passing on the information needed for protein synthesis. In most cellular organisms, DNA is organized on chromosomes located in the nucleus of the cell.
A molecule of DNA consists of two chains, strands composed of a large number of nucleotides, that are linked together to form a chain. These chains look like a twisted ladder and are called a double helix. Each nucleotide consists of three units: sugar molecules called deoxyribose, a phosphate group, and one of four different nitrogen containing compounds, also called bases. The four are adenine (A), guanine...
