DNA glycosylases are specialized enzymes that play a crucial role in the repair of damaged DNA. They recognize and remove specific damaged bases from the DNA strand, which helps maintain the integrity of the genetic material. By excising these faulty bases, DNA glycosylases prevent mutations that could lead to various diseases, including cancer. After a base is removed, the DNA repair process continues with other enzymes that fill in the gap and restore the DNA to its original state. This repair mechanism is essential for cellular health and proper functioning, ensuring that the genetic information is accurately preserved over time.
