Abstract excerpt
Two genome sequences of Escherichia coli K-12 substrains, one partial W3110 and one complete MG1655, have been determined by Japanese and American genome projects, respectively. In order to estimate the rate of nucleotide changes, we directly compared 2 Mb of the nucleotide sequences from these closely-related E. coli substrains. Given that the two substrains separated about 40 years ago, the rate of nucleotide...
