Answer to Question #342807 in Genetics for Dds

Question

explain why mismatch repair is the more important for the accuracy of DNA Replication

Answer 1

Because, for example, DNA polymerase synthesizes a DNA chain quite quickly and not always without errors. If errors are nevertheless detected, the same DNA polymerase mismatches repair, removing nucleotides at the site of the error and after it, and resynthesizing the DNA strand. And thus mismatch repair is the main identifier that the DNA chain synthesized correctly and there will be no mutations.
