title: [A new family of widely propagated MB1-repeats in the human genome].
abstract: A new family of repeats--i.e. MB1 repeats family--the number of copies of which per a human genome constitutes a few hundreds of thousands of copies has been revealed in a human gemone by computer analysis of a noncanonical similarity of nucleic acid sequences. The numbers of that family of repeats have also been revealed in the genomes of mouse and rat, they have been identified as mirror--reflected copies--in purines and pyrimidines--of B1 repeats in the genome of mouse and the Alu repeats in the human genome. The MB1 repeats tend to remain most similar at a length of 70 b.p. They are not flanked by short repeats, neither contain poly(A) region at the 3' end, by which they differ from the repeats of the SINE family. It has been assumed that the member of the Alu repeats family and the MB1 repeats family can form a so called H-form of DNA. The mirror-reflected repeat family could have been formed by replication of parallel DNA strands.
