To determine how nonrandom directional mutation pressure drives variation in DNA base composition and influences neutral molecular evolution across diverse organisms.
Applied a theoretical framework of directional mutation pressure to analyze newly available DNA sequence data across multiple taxa.
Evaluated the neutrality of directional mutation pressure against natural selection using newly formulated quantitative parameters.
Analysis revealed that directional mutation pressure toward altered guanine-plus-cytosine content affects virtually all examined organisms.
Identified two apparently universal constants governing the interaction between directional mutation pressure and sequence neutrality.
Demonstrated that directional mutation pressure accounts for base composition variation between bacteria and regional GC heterogeneity in vertebrate genomes.
