Compositional transitions in the nuclear genomes of cold-blooded vertebrates.

Journal of molecular evolution - 1 Oct 1990

Bernardi G, Bernardi G

Abstract excerpt

The compositional properties of DNAs from 122 species of fishes and from 18 other cold-blooded vertebrates (amphibians and reptiles) were compared with those from 10 warm-blooded vertebrates (mammals and birds) and found to be substantially different. Indeed, DNAs from cold-blooded vertebrates are characterized by much lower intermolecular compositional heterogeneities and CsCl band asymmetries, by a much wider...
