All these methods are collectively termed as DNA REPAIR mechanisms. Similar to DNA replication, transcription and translation, the process of DNA repair is also a prime molecular event in the cells which is very
To avoid the danger of mutations and changing genetic information, a cell is capable to switch on multiple mechanisms of DNA repair that remove damage and restore native structure. In many cases, removal of the same damage may involve several alternative pathways; this is very important for DNA...
Despite this, new chemical insights continue to be uncovered, including recent findings that may explain newly discovered functions for many DNA polymerases in DNA repair and mutation. Some of these reactions involve non-Watson–Crick base-pairing. In addition, certain DNA polymerases have been ...
DNA Repair: How MutM Finds the Needle in a HaystackDNA/meMetabolismDNARepair/phPhysiologyDNA-FormamidopyrimidineGlycosylase/meMetabolismEscherichiacoliHigh-resolution crystal structures of DNA complexes with the bacterial MutM protein show how the enzyme feels its way around the double helix in search ...
Genetic studies in yeast indicate that RNA transcripts facilitate homology-directed DNA repair in a manner that is dependent on RAD52. The molecular basis for so-called RNA−DNA repair, however, remains unknown. Using reconstitution assays, we demonstr
DNA repair: DNA repair is characterized as an assortment of techniques that can be used by a cell to recognize and rectify the destruction caused to the DNA molecules that code for its genome structure. It has been found that in living cells, both regular metabolic actions and environmental co...
