Abstract excerpt
Most previous work on the evolution of mobile DNA was limited by incomplete sequence information. Whole genome sequences allow us to overcome this limitation. I study the nucleotide diversity of prominent members of five insertion sequence families whose transposition activity is encoded by a single transposase gene. Eighteen among 376 completely sequenced bacterial genomes and plasmids carry between 3 and 20...
