How dna polymerase proofreads
WebJun 19, 2024 · Figure 3.4.7. 1: Proofreading by DNA polymerase corrects errors during replication. Some errors are not corrected during replication, but are instead corrected after replication is completed; this type of repair is known as mismatch repair (Figure 3.4.7. 2 ). WebDNA primers can replace any mistakes in base-pairing b. RNA polymerase corrects any mistakes before doing RNA transcription c. Unwinding the double helix would remove any mistakes in base-pairing d.
