Molecular computer graphics representation of the B (left) and Z forms of the DNA (deoxyribonucleic acid) molecule,the genetic material of most living organisms. DNA consists of a large number of nucleotides joined together in single file to form a strand. Two strands are linked together by base-pairing via hydrogen bonding and coiled into a helix. A nucleotide consists of 3 sub-units: a deoxyribose sugar,a phosphate group & one of four different bases; adenine,thymine,cytosine,& guanine. The genetic information is determined by the arrangement of base pairs along the molecule | |
