ABSTRACT
The arrangement of nucleosomes on the nucleotide sequence of satellite DNA of Oceanian rat (Rattus rattus) has been studied. Nucleosome cores were prepared from rat liver nuclei with micrococcal nuclease, exonuclease III and nuclease Sl. From the total population of core DNA fragments, the satellite-containing fragments were selected by molecular cloning and the complete nucleotide sequence of these clones was determined. The data show that nucleosomes occupy a number of preferred positions on satellite DNA. These positions are strictly defined. Thus location of nucleosomes along the satellite sequence is non-random. Such finding may have important biological significance.
