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 essential for the ultimate survival of the cells and also for the survival of the ...
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: 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...
Scientists at the Massachusetts General Hospital examined genes that normally have the ability to repair damage to DNA in cells called XPD and XRCC1. The number of variations in these genes indicates how long a patient is likely to survive. Sarada Gurubhagavatula and her team studied variations ...
Additionally, ingredients like arsenic and nickel may disrupt the process of DNA repair, thus compromising the body's ability to fight many cancers.此外， 砷和镍等成分也许会破坏DNA修复的过程，从而损害身体对抗许多癌症的能力。In fact, about one of every three cancer deaths in the United States is...
