Abundance of the different bases in the human genome. Results on the human genome published in Science (Science 291:1304-1350 [2001]) indicate that the haploid human genome consists of 2.91 gigabase pairs (2.91 x 109 base pairs) and that 27% of the bases in human DNA are A. Calculate the number of A, T, G, and C residues in a typical human cell.
