DNA strand. Computer artwork showing the double helix structure of a DNA (deoxyribonucleic acid) molecule. DNA is composed of two strands twisted into a double helix. Each strand consists of a sugar-phosphate backbone attached to nucleotide bases. There are four bases: adenine,cytosine,guanine and thymine,which are joined together by hydrogen bonds. DNA contains sections called genes that encode the body's genetic information. The background shows molecules and a set of chromosomes (white) | |
