Computer molecular graphics showing the structure of the DNA (deoxyribonucleic acid) molecule,the material of inheritance. 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 and coiled into a helix. A nucleotide contains the sugar deoxyribose & one of four different bases thymine,adenine,cytosine,& guanine. The former two pair only with each other as do the latter. The genetic information is determined by the arrangement of these pairs along the molecule | |
