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 ]09 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.
