dna repair
81Base 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… …
82Homology directed repair — (HDR) is a mechanism in cells to repair double strand DNA lesions. This repair mechanism can only be used by the cell when there is a homologue piece of DNA present in the nucleus, mostly in G2 and S phase of the cell cycle. When the homologue… …
83Crosslinking of DNA — Crosslinks in DNA occur when various exogenous or endogenous agents react with two different positions in the DNA. This can either occur in the same strand (intrastrand crosslink) or in the opposite strands of the DNA (interstrand crosslink).… …
84recombinant DNA technology — Genetics. any of various techniques for separating and recombining segments of DNA or genes, often employing a restriction enzyme to cut a gene from a donor organism and inserting it into a plasmid or viral DNA for transplantation into a host… …
85Direkter DNA-Schaden — Durch DNA Reparatur Mechanismen können Zellen schadhafte Veränderungen der DNA Struktur in einer Zelle beseitigen. Solche Schäden in der DNA können spontan im Verlauf der DNA Replikation oder durch die Einwirkung mutagener Substanzen, extremer… …
86Indirekter DNA-Schaden — Durch DNA Reparatur Mechanismen können Zellen schadhafte Veränderungen der DNA Struktur in einer Zelle beseitigen. Solche Schäden in der DNA können spontan im Verlauf der DNA Replikation oder durch die Einwirkung mutagener Substanzen, extremer… …
87Methylated-DNA—(protein)-cysteine S-methyltransferase — methylated DNA [protein] cysteine S methyltransferase Identifiers EC number 2.1.1.63 CAS number 77271 19 3 …
88nucleotide excision repair — (NER) repair of bulky lesions introduced into DNA by damage, such as that induced by ultraviolet light; at least 30 proteins are involved and the process consists of recognition of the lesion, strand separation at the site, single strand incision …
89Mismatch repair — A system within the cell for correcting errors in DNA that works by detecting and replacing bases in the DNA that are wrongly paired (mismatched bases). The system repairs the mismatch. When there is a mismatch in the DNA, a mismatch correction… …
90Digital DNA — is a public art sculpture commissioned by the Palo Alto Public Arts Commission for Lytton Plaza in Downtown Palo Alto, California. It was created by Adriana Varella and Nilton Malz and installed in 2005. Digital DNA, Palo Alto, CA Contents …
