DNA molecule. Computer artwork of the molecular structure of a DNA (deoxyribonucleic acid) double helix. DNA carries the genetic code,which controls and transmits an organism's hereditary traits. The helix is composed of two twisting sugar-phosphate strands,linked on the inside of the helix by complementary pairs of nucleotide bases. There are four types of nucleotide base; adenine,guanine,cytosine and thymine. The sequence of base pairs,arranged in discrete segments known as genes,determines the genetic code | |
