Molecular Features of Heterochromatin Condensation,o-called satellite DNA in mouse and man. Based on these studies we hypothesize that DNA structure, but not primary sequence ., is a fundamental aspect of heterochromatin and that a collection of nonhistone chromosomal proteins recognize this structure and/or each other to mediate differential condensation.

This could be performed by using molecular tools which allow each of the two parental chromosomes 21 to be distinguished. Possible markers suitable for this purpose are DNA fragments that exhibit length polymorphisms.

We have combined immunofluorescence with primed . hybridization (PRINS) techniques to study the organization of repetitive DNA families in relation to chromosomal proteins located at centromeres in both man and mouse species.

The appearance in Bloom’s syndrome of symmetrical quadriradials between the sister chromatids in homologous chromosomes (Chaganti, Schonberg & German, 1974) further implies that interchromosomal exchange can occur in mitotic cells of humans.

Mario Spiezio,Maria De Freitas Martinhom, fidelity of chromosome distribution during cell division is of obvious importance. Cells must not only regulate the spatial arrangement and distribution of chromosomes to ensure their equal partition but also tightly coordinate the start of poleward chromosome movement in mitosis with the concurrent orderly return to interphase.
