Genetic research. Conceptual computer artwork of part of a DNA (deoxyribonucleic acid) molecule on a computer screen. This represents computers being used in genetic research. The DNA double helix is composed of two twisting sugar-phosphate strands (pink and purple) linked by nucleotide base pairs (green). The sequence of the bases encodes genetic information. The decoding of the human genome was accomplished with the help of computer programs to interpret the results and store the data.
