Final answer:
Base excision repair involves multiple glycosylases that recognize and remove specific damaged bases.
Step-by-step explanation:
Base excision repair (BER) is a DNA repair mechanism that fixes damage to a single nucleotide in the DNA. In this process, specific enzymes called glycosylases remove the damaged base. There are several glycosylases involved in base excision repair, each recognizing and removing a specific type of damaged base.
