Abstract
The genomes of the extremely halophilic bacteria, H. halobium and H. volcanii, contain many repeated sequences. These sequences comprise many families, seem to be highly mobile and are arranged in both clustered and dispersed fashions within these genomes. At least some repeated sequences are more strongly conserved between the 2 species than are unique sequence DNA.
