DNA Glycosylase

DNA glycosylase is an enzyme that plays a crucial role in maintaining DNA integrity. It detects and removes damaged or abnormal bases—building blocks of DNA—that may have been altered by factors like radiation or chemicals. By locating and cutting out these damaged bases, DNA glycosylase initiates a repair process that ensures the DNA remains accurate and functional. This is a key step in the cell’s natural defense system against mutations, helping to prevent diseases such as cancer and supporting overall genetic stability.
