The vertebrate genome: isochores and evolution.

Abstract excerpt

Vertebrate genomes are mosaics of isochores--namely, of long (> 300 kb), compositionally homogeneous DNA segments that can be subdivided into a small number of families characterized by different GC levels. In the human genome (which is representative of a number of mammalian genomes, and, more broadly, of the genomes of warm-blooded vertebrates), the compositional range of isochores is 30%-60% GC, and five...
