21DNA methylation — n the enzymatically controlled methylation of a nucleotide base (as cytosine in eukaryotes) in a molecule of DNA that plays a role in suppressing gene expression * * * the postsynthetic addition of methyl groups to specific sites on DNA… …
22DNA polymerase eta — (Pol η) is a eukaryotic DNA polymerase involved in the DNA repair by translesion synthesis. The gene encoding DNA polymerase eta is POLH, also known as XPV, because loss of this gene results in the disease Xeroderma Pigmentosum Variant.… …
23DNA glycosylase — (= DNA glycosidase) Class of enzymes involved in DNA repair. They recognize altered bases in DNA and catalyse their removal by cleaving the glycosidic bond between the base and the deoxyribose sugar. At least 20 such enzymes occur in cells …
24DNA 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… …
25DNA polymerase beta — Polymerase (DNA directed), beta PDB rendering based on 1bno …
26DNA polymerase — 3D structure of the DNA binding helix turn helix motifs in human DNA polymerase beta A DNA polymerase is an enzyme that helps catalyze in the polymerization of deoxyribonucleotides into a DNA strand. DNA polymerases are best known for their… …
27DNA polymerase lambda — Polymerase (DNA directed), lambda Rendering based on 1xsn of pol λ bound to a DNA strand containing a 1 nt gap …
28DNA — For a non technical introduction to the topic, see Introduction to genetics. For other uses, see DNA (disambiguation). The structure of the DNA double helix. The atoms in the structure are colour coded by element and the detailed structure of two …
29DNA methylation — Illustration of a DNA molecule that is methylated at the two center cytosines. DNA methylation plays an important role for epigenetic gene regulation in development and disease. DNA methylation is a biochemical process that is important for… …
