Genes can also be turned off by RNA when it is in the form of antisense transcripts, noncoding RNAs, or RNA interference. RNA might affect gene expression by causing heterochromatin to form, or by triggering histone modifications and DNA methylation (Egger et al ., 2004).or example, methylation of a particular lysine (K9) on a specific histone (H3) that marks silent DNA is widely distributed throughout heterochromatin. This is the type of epigenetic change that is responsible for the inactivated X chromosome of females.
