5-Hydroxymethylcytosine is an altered version of cytosine, a fundamental component of DNA. Its discovery has brought significant insights into the realm of epigenetics, shedding light on its diverse involvement in numerous biological processes. This relatively recent breakthrough has established 5-hmC as a key player in gene expression, DNA methylation, and various cellular functions. Extensive research in the field of epigenetics has confirmed its pivotal role in regulating gene expression, DNA methylation, and other essential cellular functions.
