Computer graphics image of DNA,showing its double helix structure. The DNA molecule's atoms are colour coded: carbon atoms are white,nitrogen blue,oxygen red,phosphorus green. DNA (deoxyrib- onucleic acid) consists of two linked strands of nucleotides,coiled into a helix.. The strands are joined by the pairing of organic bases 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 order of these pairs. The image shows the B form of DNA (B-DNA) | |
