title: [EcoRI- and BamHI-families of repeated sequences in mustelids].
abstract: The restriction enzymes EcoRI and BamHI digest the genomic DNAs from six mustelids species Mustela lutreola, M. vision, M. erminea, M. sibirica, Vormela peregusna, producing repeated fragments varying in length. Some fragments were hybridized to chromosomes and restriction digests of DNAs from some mustelids and other mammals. The 0.7 kb EcoRI repeats from DNA of M. erminea are dispersed over chromosomes of carnivors. The 1.35, 1.9 and 2.7 kb BamHI repeats from DNA of polecat M. putorius furo are specific for mustelids. These repeats demonstrate interspecific variation in length and the number of copies. All BamHI repeats have no strict tandem organization. The 1.9 kb BamHI repeats are concentrated in the heterochromatic pericentromeric regions and additional chromosome arms. The 1.35 kb BamHI repeats are only located in the centromeric regions of chromosomes of five species and are absent in Vormela peregusna.
