Repeated Sequences in the Genomes of Halobacteria

Abstract

Molecular cloning and Southern hybridization techniques have allowed us to show that the genome of Halobacterium halobium contains a large number of repeated sequences, comprising many families. Some elements from different families may be clustered in the genome. Rearrangements (transpositions?) affecting such elements occur frequently and spontaneously. Some H. halobium repeat sequence families are also represented in the genome of H. volcanii.
