DNA oxidation — is the process of oxidative damage on Deoxyribonucleic Acid. It occurs most readily at guanine residues due to the high oxidation potential of this base relative to cytosine, thymine, and adenine. It is widely believed to be linked to certain… … Wikipedia
DNA damage theory of aging — The DNA damage theory of aging proposes that aging is a consequence of unrepaired DNA damage accumulation. Damage in this context includes chemical reactions that mutate DNA and/or interfere with DNA replication. Although both mitochondrial and… … Wikipedia
DNA demethylation — is a process of removal of methyl group from nucleotide in DNA. DNA demethylation could be passive and active. Passive process takes place in the absence of methylation of newly synthesised DNA strands by DNMT1 during several replication rounds… … Wikipedia
