Abstract/OtherAbstract:
The in situ nick translation procedure performed on fixed meiotic chromosomes partially cleaved with restriction endonucleases shows a different staining of homologous heterochromatic regions, which could be explained through a differential restriction endonuclease cleavage. Mutations occurring before massive tandem duplication and involving those DNA motifs that produce these heterochromatic blocks, together with the absence of DNA recombination that characterizes these particular regions, could explain the observed results. This method for chromosome labelling is most useful to demonstrate a certain level of heterochromatin heterogeneity that is present in the genome of living species but remained cryptic to other techniques that are also able to induce longitudinal differentiation of the chromosomes.
