WebSep 24, 2024 · In mice, chromatin inversion occurs during the first few weeks of postnatal life when committed rod cells also exit the cell cycle and become post mitotic . During this time, heterochromatin from the nuclear periphery is relocated to the nuclear interior and forms a dense structure in the center of the nucleus. Chromatin is a complex of DNA and protein found in eukaryotic cells. The primary function is to package long DNA molecules into more compact, denser structures. This prevents the strands from becoming tangled and also plays important roles in reinforcing the DNA during cell division, preventing DNA damage, … See more Chromatin undergoes various structural changes during a cell cycle.

Heterochromatin is a tightly packed form of DNA or condensed DNA, which comes in multiple varieties. These varieties lie on a continuum between the two extremes of constitutive heterochromatin and facultative heterochromatin. Both play a role in the expression of genes.
