摘要
DNA was extracted from various rodent-human somatic cell hybrids that contained single or a few human chromosomes. These DNAs were examined by a combination of restriction endonuclease digestion, gel electrophoresis, and filter hybridisation to radioactive satellite DNA probes following transfer of the denatured restriction fragments from a gel to a nitrocellulose filter. In this way the arrangement of sequences homologous to human satellite III were examined on human chromosomes 1, 7, 11, 15, 22 and X. It was found that the distribution of restriction endonuclease sites within satellite III DNA is different on different chromosomes. © 1979 Springer-Verlag.
