Nucleotide sequence of bovine 1.723 satellite DNA

The nucleotide sequence of the bovine 1.723 satellite DNA repeated unit was determined. The 680 bp long period of this satellite DNA does not show any significant sequence similarities with the known bovine satellite DNAs. Short repetitive sequences which are parts of 680 bp long repeated units do not form any orderly periodical structure. It seems, however, that the basic repeated unit of the 1.723 bovine satellite DNA has been formed by successive duplications of two, about 100 bp long sequences. The sequence divergence between different copies of the 680 bp repeated unit was also analyzed.
