DNA molecule. Computer artwork of a molecule of deoxyribonucleic acid (DNA). DNA is composed of two strands twisted into a double helix. Each strand consists of an outer sugar-phosphate backbone (thick silver line) with nucleotide bases attached (lines inside helix). There are four different bases: guanine,cytosine,thymine and adenine. Guanine always pairs with cytosine and adenine always pairs with thymine. DNA contains sections,called genes,which encode the body's genetic information. Genes determine each cell's structure,function and behaviour | |
