Computer-generated model of a molecule of deoxyribonucleic acid (DNA). DNA is the genetic material of most organisms,and plays a central role in the passing of hereditary characteristics. DNA consists of a double helix of nucleotides,each of which consists of a deoxyribose phosphate molecule combined with a base group. The bases,seen here as magenta,are hydrogen bonded to link the two helix chains. The bases always bond thymine to adenine and cytosine to guanine. DNA replicates by the two helices seperating and new nucleotides added to each resultant helix,the base pairing assuring that exact duplicates of the original DNA are made | |
