Abstract: | The stability of certain dicentric chromosomes in humans seemsto result from inactivation of one centromere, yielding a functionallymonocentric chromosome. Centromere protein C (CENP-C) was previouslyshown to be present at active centromeres but absent from theinactive centromere of one homologous dicentric rearrangement.We have combined indirect immunofluorescence detection of CENP-Cand fluorescence in situ hybridization with chromo-some-specific |
