A major PvuII satellite DNA has been cloned from a South American octodontid rodent of the genus Ctenomys (C. porteousi). The satellite monomer, termed RPCS, is 337 bp in size and 42% G + C. Analysis of the nucleotide sequence demonstrates that RPCS is not composed of a series of shorter repeats. RPCS-related sequences were found in 11 of 12 Ctenomys species analyzed by hybridization under high-stringency conditions. The only negative species, C. opimus, was reactive under low-stringency… CONTINUE READING
