Bovine 1.709 satellite. Recombination hotspots and dispersed repeated sequences

The nucleotide sequence of 3800 base-pair repeated unit of bovine 1.709 satellite was determined. The 3800 base-pair unit is not internally repeated and contains members of at least three different families of elements that are dispersed in the bovine genome. Two of three elements are associated with extensive length polymorphism within the satellite repeat unit. One of these comprises the 3' end of the bovine Alu-like sequences; the second is composed of C-A dinucleotides.
