Inserted sequences in bovine satellite DNA's

RE Streeck

The nucleotide sequence of the 1413-base-pair repeat unit of bovine 1.711a satellite DNA (density in cesium chloride, 1.711 grams per cubic centimeter) has been determined. The repeat unit contains two segments consisting of variants of a basic 23-base-pair sequence that is closely related to sequences of bovine 1.706 satellite DNA. A third segment of the repeat unit contains an unrelated 611-base-pair sequence that is not internally repetitive. This segment is flanked by inverted repeats of 8 base pairs and, on one side, by a direct repeat of the terminal sequence. A related segment is present in bovine 1.711b satellite DNA and is inserted into sequences derived from the 1.715 satellite. These nucleotide sequences suggest the timing of some of the stages in the evolution of these complex, closely related satellite DNA's and indicate the mechanisms inherent in their divergence from a common ancestor.
