Abstract

Statistical analysis of frequency occurrence of short words in complete genomes reveals the existence of a set of universal lengths common to all extant complete microbial genomes. This phenomenon is consistent with a model for genome growth in which primitive genomes grew mainly by maximally stochastic duplications of short segments from an initial length of about 200 nucleotides. The relevance of these results to the so-called RNA world in which life began and evolved before the rise of proteins is discussed.
