Ok, In simple terms, DNA methylation is a natural process that involves the addition of small chemical tags called “methyl groups” to the DNA molecule. These methyl groups can be considered tiny “flags” attached to specific parts of the DNA
The effects of DNA methylation and Histone acetylation on Gene Expression
DNA methylation and histone acetylation are two epigenetic mechanisms that regulate gene expression. Methylation is adding a methyl group to a cytosine nucleotide in DNA. At the same time, acetylation adds an acetyl group to a lysine residue in a
