    DNA methylation - Wikipedia

    • DNA methylation is a biological process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription. In mammals, DNA methylation is essential for normal development and is associat… See more

    Conserved function of DNA methylation

    The DNA methylation landscape of vertebrates is very particular compared to other organisms. In mammals, around 75% of CpG dinucleotides are methylated in somatic cells, and DNA methylation appears a… See more

    In mammals

    DNA methylation patterns are largely erased and then re-established between generations in mammals. Almost all of the methylations from the parents are erased, first during gametogenesis, and again in early … See more

    Function of DNA methylation: DNA methylation is an important epigenetic alteration and crucial for our genome. It is extensively involved in gene expression and regulation. To do so, DNA methylation is significantly reported on CpG, intergenic and gene body parts. It’s also reported during X chromosome inactivation.
