Identification and Characterization in silico of Meiotic DNA

A method of in silico search for specific repetitive DNA sequences related to the synaptonemal complex (meiDNA) in mammalian genomes was developed. A study of the distribution of these repeats over chromosomes revealed their scarcity on the Y chromosome and a decrease in recombination frequency in regions enriched in meiDNA. The results are discussed in context of the model of the looplike meiotic chromosome organization during the formation of the synaptonemal complex.__________Translated from Genetika, Vol. 41, No. 5, 2005, pp. 697–701.Original Russian Text Copyright © 2005 by Grishaeva, Dadashev, Bogdanov.
