DNA Repair Mechanisms Despite the remarkable accuracy of DNA replication, errors can occur. Additionally, DNA can be damaged by various factors, such as exposure to radiation or chemicals. To maintain the integrity of genetic information, cells have evolved several DNA repair mechanisms. One of the...
Once cellular DNA damage occurs, the DDR is activated to protect damaged DNA integrity. The cell cycle is paused to provide cells an opportunity to activate DNA repair mechanisms. When the DNA damage is severe, cell death programs are activated. Dashed arrows indicate altered mechanisms. Alteration...
DNA repair, any of several mechanisms by which a cell maintains the integrity of its genetic code. DNA repair ensures the survival of a species by enabling parental DNA to be inherited as faithfully as possible by offspring. It also preserves the health of an individual. Mutations in the ...
Improved nonviral gene editing would be a powerful approach to unraveling DNA repair mechanisms, a useful laboratory technique and a promising strategy for the treatment of a multitude of diseases3. One high-efficiency nonviral gene editing strategy codelivers ribonucleoprotein (RNP) formulations ...
DNA repair mechanisms DNA damage responseis a natural process by which cells maintain genome integrity and prevent harmful mutations[142, 143]. Platinum-based drugs can act by inducing direct or indirect DNA damage, causing inhibition during the progression of cell-cycle progression. This causes cell...
cells has evolved many methods to overcome and rectify different types DNA damages. All these methods are collectively termed asDNA REPAIRmechanisms. Similar to DNA replication, transcription and translation, the process of DNA repair is also a prime molecular event in the cells which is very essen...

Mutational signatures have become a pillar of cancer genome analysis because they may shed light on the carcinogens cancer cells have been exposed to, and the repair mechanisms that were perturbed. However, not all observed mutational signatures and their individual facets are fully understood. An ex...
DNA mismatch repair (MMR) is a highly conserved biological pathway that plays a key role in maintaining genomic stability. The specificity of MMR is primarily for base-base mismatches and insertion/deletion mispairs generated during DNA replication and r
