WebMar 30, 2024 · The failure to detect replication forks arrested at the 3′ end of inactive rRNA gene copies and the fact that most DNA encoding rRNA (rDNA) is replicated in the same direction as transcription suggest that replication forks seldom originate from origins of replication located immediately downstream of inactive genes. WebIn adults, the Xist gene is expressed only on the inactive X chromosome (Xi). It also appears that the RNA might direct DNA methylation to the silent X, further compacting it.

One cell might shut down the paternal X, while its next-door neighbor might shut down the maternal X instead. All the cells descended from each of these original cells will maintain the same pattern of X-inactivation. WebIn females one random X chromosome in each cell is inactive and becomes the Barr body. Some genes can keep other genes from being expressed through epistasis.
