Caption

DNA helices. Models of part of the double helix of DNA (deoxyribonucleic acid), which is formed of spiralling paired strands of sugar phosphates that are linked by nucleotide base pairs. There are four bases: adenine, thymine, guanine & cytosine (coloured links) that when paired form struts, as on a ladder. The arrangement of the bases along a helix of DNA is the genetic code for protein synthesis and the functioning and growth of every living organism. DNA is found in cell nuclei.
