Genetic research. Conceptual computer artwork showing part of a DNA molecule (down right) and the letter codes for the nucleotide bases: adenine (A),thymine (T),cytosine (C) & guanine (G). DNA (deoxyribonucleic acid) is a double helix molecule that carries the genetic code,which controls and transmits an organism's hereditary traits. DNA is made up of two strands of sugar-phosphate groups. The strands twist to form the double helix shape,and are cross-linked by complementary pairs of nucleotide bases (horizontal links). The sequence of base pairs,arranged in discrete segments known as genes,determines the genetic code | |
