User:PanicWallet/Chormatin mobility

From Wikipedia, the free encyclopedia

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.[1]


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