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 Chemical synthesis synthesised DNA strands by DNMT1 during several replication rounds for example, upon 5 Azacytidine treatment . Active DNA demethylation occurs via active dismiss of methyl group. Examples of active DNA demethylation All the cases of DNA demethylation could be divided on global genome wide and specific when just specific sequences are demethylated . The genome wide DNA demethylation occurs In mammals In male pronucleus of zygote immediately after fertilization Possibly in the primordial germ cells PGCs of 11.5 12.5 day old embryos Possibly in amphibia during midblastula transition Examples of specific DNA demethylation Gene imprinting during plant reproduction Electroconvulsive ... epigenetic DNA demethylation and adult neurogenesis. journal Science date 2009 02 20 volume 323 issue ... by TET1 Promotes Active DNA Demethylation in the Adult Brain journal Cell date 2011 04 29 volume ... mechanisms of active DNA demethylation There are several proposed hypothetical mechanisms of active DNA demethylation A Direct removal of 5 methylcytosine Direct removal of methyl group.

A DNA bank is a wikt repository repository of DNA , usually used for research. The NIAS DNA Bank, for example, collects the DNA of agricultural organisms, such as rice and fish , for scientific research. Most DNA provided by DNA banks is used for studies to attempt to develop more productive or more environmentally friendly agricultural species. Some DNA banks also store the DNA of rare or endangered species to ensure their survival. The Asia First DNA Bank Establish in Lucknow City Of India And Worlds Second DNA Bank. See also DNA database , an electronic database of the results of DNA fingerprinting of many individuals, used for forensic purposes.
