Renewing DNA integrity by cell repair systems

  • L. L. Lukash


The four of six main cell repair systems have been reviewed. Some of them have been studied by Nobel laureates of 2015 year in the field of chemistry. The common title of their work is “For investigation of DNA repair mechanisms”. Numerous primer damages of DNA induced by exogenous and endogenous factors are corrected by complex cell systems including repair enzymes and other proteins. Mutational changes in the genes coding the repair enzymes are the most dangerous because they dramatically increase mutation frequency in pro- and eukaryotic cells. But due to the constant and correct action of cell repair enzymes DNA integrity is renewing, that is why the organisms on our planet are still alive and functionally active.

Keywords: DNA repair, reparative enzymes, pro- and eukaryotic cells, primer damages, mutations.
