Computer graphics image of DNA,showing its double helix structure & base pairing. DNA (deoxyribonuc- leic acid) consists of two linked strands of nucleotides (dark blue & purple),coiled into a helix. The strands are joined by the hydrogen bonding of pairs of organic bases (light blue & yellow) on adjacent nucleotides. Each nucleotide contains the sugar deoxyribose & one of four bases: thymine (T),adenine (A),cytosine (C),& guanine (G). T pairs up only with A,C with G. The genetic information is determined by the ordering of these pairs. The image shows the B form of DNA (B-DNA) | |
