Heterochromatin is a form of chromatin that is densely packed—as opposed to euchromatin, which is lightly packed—and is found in the nucleus of eukaryotic cells. Whereas euchromatin allows the DNA to be replicated and transcribed, heterochromatin is in such a condensed structure that it does not enable …

These fibers are condensed into chromosomes during mitosis, or the process of cell division. However, packaging of chromatin into chromosomes that we are most familiar with occurs only during a few stages of mitosis.
