User:PanicWallet/Chormatin mobility

Chromatin movement Chromatin is not static but is highly dynamic. Nucleosomes (the core particle of chromatin) are constantly being modified either by the exchange or post-transcriptional modification of histones. Nucleosome spacing also affects chromatin structure allowing it to be more or less accessible. Chromatin can also move as a fiber within the nucleus in a manner that is ATP dependent and is not simply temperature-dependent Brownian motion.

Why move chromatin? Homology search Get out of heterochromatin Get to a special repair compartment
