DNA Repair Mechanisms
The process of base excision involves detecting and removing abnormal bases, leading to the repair of DNA by filling in gaps with the correct nucleotides. However, if the complementary strand has already been altered, mutations can occur. Mismatch repair serves as a secondary mechanism to correct mistakes made during DNA synthesis, distinguishing between old and new strands through methylation, which helps ensure the integrity of genetic information.In this clip
