Web27. feb 2024. · The mismatch is the key factor in achieving the amplification. Weak mismatch elevates chances of amplification and so add strong mismatch to avoid false-amplification near the 3’-OH end of the primer (at -2 position ideally). Mismatch prevents binding to the non-complementary sequence and terminates amplification. WebOne primer has one base pair mismatch at the 3' end. I would like to know how will that one base mis-match at the 3' end can compromise DNA polymerase reaction. WebIn contrast, the single-base mismatched (SM) duplex (CP/SM) contains a single C–C mismatch-adjacent to the 5′ abasic site (C), inhibiting Exo III endonucleolytic digestion.
