Silencing,
Heterochromatin and DNA Double Strand Break Repair
Although I have no doubt that many breakthroughs in our understanding of chromatin, chromatin regulation, and DNA repair lie in our future, presently this is a new line in inquiry. As such there are many, many unanswered questions.

Mechanisms of Gene Silencing by
Heterochromatin Protein 1
Heterochromatin Protein 1 (HP1) is a chromosomal protein involved in gene silencing.
The permanent association of centromere and telomere heterochromatin has
created a new gene linkage groups and reduced the chromosome number. For
instance, in an ancestral species E. impar the constitutive heterochromatin is in
the ...

The Principles of Clinical Cytogenetics
Alpha-satellite DNA is a repeat of a 171-basepair sequence organized in a
tandem array of up to a million basepairs or more in total length. Alpha-satellite
DNA is generally not transcribed and is located in the heterochromatin
associated with ...

THE HUMAN GENOME: A User's Guide
If we look at different cell types or cells in different metabolic states we will see
some changes to this pattern, since some areas of constitutive heterochromatin
contain genes but will stain as if gene-poor if those genes are not being used.

These relate to the overall activity of genes: euchromatin to active genes,
heterochromatin to inactive genes. A. A histone-free chromosome under the

Heterochromatin propagates from a nucleation event Key concepts •
Heterochromatin is nucleated at a specific sequence and the inactive structure
propagates along the chromatin fiber. • Genes within regions of heterochromatin
are ...
Microtus agrestis,136 appear to lack highly repetitive DNA in much of their
heterochromatin, but instead have only moderately repetitive sequences. In no
case is it possible to state that any block of heterochromatin contains exclusively
one ...
