We studied the organization of telomeric, major and minor satellite DNA sequences located in the pericentromeric regions of mouse telocentric and Robertsonian metacentric chromosomes by high-resolution fluorescence in situ hybridization. Molecular data have already proved that in telocentrics, from the physical chromosome end, telomeric sequences are followed by minor and then by major satellite DNA. We showed that the three families of repetitive DNA are organized as uninterrupted long-range cluster repeats and that there is no intermingling between telomeric and minor satellite DNA or between the major and the minor tandem repeats or with non-satellite DNA. The pericentromeric region of metacentric chromosomes consists of a small block of minor satellite DNA sandwiched between two blocks of major satellite DNA.
