Abstract
The distributions of 3 human ribosomal gene polymorphisms among individual chromosomes containing nucleolus organizers were analyzed by using mouse-human hybrid cells. Different nucleolus organizers can contain the same variant, suggesting the occurrence of genetic exchanges among ribosomal gene clusters on nonhomologous chromosomes. Such exchanges appear to occur less frequently in mice. This difference is discussed in terms of the nucleolar organization and chromosomal location of ribosomal gene clusters in humans and mice.This publication has 27 references indexed in Scilit:
