Base excision repair — (BER) is a cellular mechanism that repairs damaged DNA throughout the cell cycle. Repairing DNA sequence errors is necessary so that mutations are not propagated or to remove lesions that may lead to breaks in the DNA during replication.Single… … Wikipedia
DNA nanotechnology — seeks to make artificial, designed nanostructures out of nucleic acids, such as this DNA tetrahedron.[1] Each edge of the tetrahedron is a 20 base pair DNA double helix, and each vertex is a three arm junction. DNA n … Wikipedia
DNA-Replikation — DNA Replikation. Die Doppelhelix wird durch die Helicase und die Topoisomerase geöffnet. Danach setzt die Primase einen Primer und die … Deutsch Wikipedia

DNA laddering — (left) visualised in an agarose gel by ethidium bromide staining. A 1 kb marker (middle) and control DNA (right) are included. DNA laddering is a phenomenon seen in laboratory tests; it is a sensitive indicator of programmed cell death … Wikipedia
DNA glycosylase — DNA glycosylases are a family of enzymes involved in base excision repair, classified under EC number EC 3.2.2. Base excision repair is the mechanism by which damaged bases in DNA are removed and replaced. DNA glycosylases catalyze the first step … Wikipedia
