In metazoa, clusters of repetitive DNA are packaged into heterochromatin at the centromere region (Figure 1a, b). Typically, heterochromatin forms at pericentromeric (near the cellular centromere) and telomere regions that comprise repetitive DNA sequences (Bühler and Gasser 2009).
Where is heterochromatin most likely found?
Heterochromatin Domain
Heterochromatin is a cytologically dense material that is typically found at centromeres and telomeres. It mostly consists of repetitive DNA sequences and is relatively gene poor. Its most notable property is its ability to silence euchromatic gene expression.
What phase is heterochromatin found in?
Heterochromatin, which is more condensed and rarely transcribed, usually replicates in late S phase. Here, we report significant deviation from this correlation in the fission yeast, Schizosaccharomyces pombe. We found that heterochromatic centromeres and silent mating-type cassettes replicate in early S phase.
