DNA helix. Model showing the double helix of DNA (deoxyribonucleic acid). The double helix consists of two spiralling strands of sugar phosphates that are linked by nucleotide base pairs. These pairs form struts,as on a ladder. The arrangement of the four types of nucleotide base along a helix of DNA forms the genetic code for protein synthesis and the functioning and growth of every living organism. DNA is found in cell nuclei | |
