Question

Which statements explain why polymerases have an error rate of 1 in 10 -10? Select one or more: O a. All of the above contribute to the polymerases' exceptionally low error rate. O b. Errors naturally occur infrequently because the tautomeric form of the nucleotieds allow them to triple bond with bases but this is a highly unusual event. O c. The polymerase has exonuclease activity which removes miss-pairs which increases the polymerase accuracy by an additional 10 - 10 O d. Cells, even bacteria, have a separate enzyme system that repairs the mismatched base pairs remaining after replication. O e. There are several types of polymerase, some of which are specialized to perform 5'-3' exonuclease activity, which is distinct from the 3-5'proofreading exonuclease
