Аннотация

The uniform distribution of satellite DNA II and IV has been revealed using in situ hybridization and differential staining in centromeric regions of autosomes. The sex chromosomes have not found such nucleotide blocks. There is only minor satellite IV block inside Y chromosome short arm. The Y chromosome has got some (TG)n enriched blocks distributed also among other parts of genome and one copy of sequences like human ZFY gene. The high repetitive fraction of bovine genomic DNA have not revealed RFLP. However, the difference has been found by blot hybridization between genomic organization of satellite IV in cattle and yak chromosomal DNA. Non-Mendelian distribution of some such nucleotide blocks has been obtained for interspecies crosses of cattle and yak.

Переведенное названиеThe characteristics of chromosomal distribution and of the variability of the multiply repeating DNA fraction of the genome in Bos taurus L.
