DNA glycosylase is an enzyme that plays a crucial role in the repair of damaged DNA. It recognizes and removes specific damaged bases from the DNA strand, which can occur due to various factors like radiation or chemical exposure. By excising these faulty bases, DNA glycosylase helps maintain the integrity of the genetic material. After the damaged base is removed, the DNA repair process continues with other enzymes that fill in the gap and restore the DNA structure. This repair mechanism is essential for preventing mutations and ensuring proper cellular function, ultimately contributing to the overall health of an organism.
