Genome sequences vary strongly in their repetitiveness and the causes for this are still debated. Here we propose a novel measure of genome repetitiveness, the index of repetitiveness, Ir, which can be computed in time proportional to the length of the sequences analyzed. We apply it to 336 genomes from all three domains of life. The expected value of Ir is zero for random sequences of any G/C content and greater than zero for sequences with excess repeats. We find that the Ir of archaea is… CONTINUE READING
