Genome Evolution: Overview

The genome is the total genetic constitution of an organism. Understanding of the structure and evolution of genomes is undergoing a revolution with ability to sequence entire genomes. A key feature in the evolution of genomes is the creation of new genes, usually by duplication.

Keywords: Archaea; repetitive DNA; concerted evolution; selfish DNA; junk DNA
