[Distribution of Drosophila melanogaster mobile genetic elements along X-chromosome and autosomes].
The distribution along Drosophila melanogaster polytene X-chromosome and autosomes of 10911 in situ hybridization sites of a broad spectrum of copialike mobile elements is investigated. It is shown that against DNA content X-chromsomal cytological sections 14 + 15 and 16 + 17 contain much less mobile elements than other chromosomal regions. These X-chromosomal regions are also characterized both by significant decrease in the meiotic recombination frequencies and the amount of poly(dC-dA).poly(dG-dT) sequences which are capable to generate the Z form of DNA.
