Mismatch repair
A mechanism that corrects mismatched base pairs that have escaped correction by the proofreading activities of the DNA polymerases.
Mispairing
Improper alignment of two nucleic acid strands.
Mismatch Repair (MMR)
Mismatch repair deals with correcting mismatches of the normal bases; that is, failures to maintain normal Watson-Crick base pairing (A-T, C-G) ...
Mismatch repair is a DNA repair mechanism which has been observed in a wide range of organisms. In bacteria, integration of foreign DNA into the chromosome occurs by a process called recombination which involves exchange of similar sequence DNA.
Mismatch Repair
After DNA is replicated, some enzymes function to locate mismatched base pairs, remove a short segment of nucleotides containing the error, and replace the segment with the correct nucleotides.
The process of DNA repair occurs through two main pathways, nucleotide excision repair (NER) and mismatch repair, and each of these pathways involves the interaction of numerous proteins.
This conversion of one allele to the other is due to base mismatch repair during recombination: if one of the four strands during meiosis pairs up with one of the four strands of a different chromosome, as can occur if there is sequence homology, ...
