Abstract

Epigenetic changes are a reversible process. The epigenetic changes are: methylation, histone modification, and non-coding RNA. Through processes such as DNA methylation, histone modification and non-coding RNA action, the chromatin state is altered, thereby influencing gene activation. Moreover, epigenetic modifications can respond to environmental exposures. DNA methylation typically silences genes by adding methyl groups to cytosine bases neighbouring guanines; chemical modifications in histone tails can either loosen or tighten DNA winding around histones, affecting accessibility to transcription factors; and non-coding RNAs can interfere with transcription or translation processes.
