DNA Demethylation

DNA demethylation is the process of removal of a methyl group from nucleotides in DNA. DNA demethylation could be passive or active. The passive process takes place in the absence of methylation of newly synthesised DNA strands by DNMT1 during several replication rounds (for example, upon 5-Azacytidine treatment). Active DNA demethylation occurs via direct removal of a methyl group independently of DNA replication.

Famous quotes containing the word dna:

    Here [in London, history] ... seemed the very fabric of things, as if the city were a single growth of stone and brick, uncounted strata of message and meaning, age upon age, generated over the centuries to the dictates of some now all-but-unreadable DNA of commerce and empire.
    William Gibson (b. 1948)
