The evolution of a family of short interspersed repeats in primate DNA.

Human DNA contains 300 nucleotide interspersed repeated sequences which mostly belong to a single family of sequences called the Alu family. This work examines the evolution of this family of sequences in primates. Bonnet monkey (Macaque radiata) DNA contains a predominant family of 300 nucleotide repeats which has nearly the same restriction map as the human Alu family and which hybridizes to human Alu family repeats under Southern blotting conditions. Prosimian (Galago crassicaudatus pangeniesis) DNA also contains a prominent group of 300 nucleotide long repeated sequences which does not have the same restriction sites as the human Alu family but which does hybridize to the human Alu family under reduced stringency conditions.
