Below is how epigenetics works, except?
A
DNA Methylation
B
Histone Methylation
C
Histone Modification
D
Non Coding RNA
Explanation: 

Detailed explanation-1: -Epigenetics is the study of how your behaviors and environment can cause changes that affect the way your genes work. Unlike genetic changes, epigenetic changes are reversible and do not change your DNA sequence, but they can change how your body reads a DNA sequence.

Detailed explanation-2: -Histone methylation is part of the most common epigenetic regulations that play important roles in developmental processes and diseases. The methylation status of lysine residues in histone proteins determines the active and silent states of surrounding genes by modulating the chromatin architecture.

Detailed explanation-3: -A common type of epigenetic modification is called DNA methylation. DNA methylation involves the attachment of small chemical groups called methyl groups (each consisting of one carbon atom and three hydrogen atoms) to DNA building blocks.

Detailed explanation-4: -Epigenetic mechanisms form a layer of control within a cell that regulates gene expression and silencing. Three different epigenetic mechanisms have been identified: DNA methylation, histone modification, and non-coding RNA (ncRNA)-associated gene silencing. More items •08-Aug-2022
