[Nucleotide sequence of DNA isolated from protein cores of rosette-like structures (elementary chromomeres) of mouse interphase chromosomes].

Data are presented on the primary nucleotide sequence of 15 DNA fragments cloned from protein cores of rosette-like structures of mouse interphase chromosomes. According to data of a computer analysis, these DNA fragments represent protein-noncoding regions of interphase chromosomes, contain nucleotide sequences causing DNA strand bending, and contain a large amount of cis-regulatory transcriptional elements and sites closely related to sites of DNA topoisomerase II cleavage. Five clones demonstrated partial length homology with satellite DNA, short and long interspersed sequences, and extrachromosomal DNA from mouse thymocytes. Six clones showed homology with sites of initiation of replication of viruses, yeast, and mice. Six clones were found to contain consensus sequences for non-homologous recombination in somatic cells and six clones contained consensus sequences of human VTR1.1 loci.
