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