Abundance, distribution, and mutation rates of homopolymeric nucleotide runs in the genome of Caenorhabditis elegans.

Abstract excerpt

Homopolymeric nucleotide runs, also called mononucleotide microsatellites, are a ubiquitous, dominant, and mutagenic feature of eukaryotic genomes. A clear understanding of the forces that shape patterns of homopolymer evolution, however, is lacking. We provide a focused investigation of the abundance, chromosomal distribution, and mutation spectra of the four strand-specific homopolymer types (A, T, G, C) >or=8...
