Gene

Non-methylated DNA at CpG islands organizes histone methylation through ZF-CxxC proteins in epigenetic biological systems. DNA and histone Methylation is catalyzed by enzymes; such methylation can be involved in hodyonr modification, regulation of gene expression, regulation of protein function, and RNA processing. Methylation of heavy metals can also occur outside biological systems. Chemical methylation of tissue samples is also one method for reducing certain histological staining artifacts. The counterpart of methylation is demethylation.

Description

A methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms — CH3. In formulas, the group is often abbreviated Me. Such hydrocarbon groups occur in many organic compounds. It is a very stable group in most molecules. While the methyl group is usually part of a larger molecule, it can be found on its own in any of three forms anion, cation or radical. The anion has eight valence electrons, the radical seven and the cation six. All three forms are highly reactive and rarely observed,
