DNAkorjausreittien
DNAkorjausreittien, which translates to DNA repair pathways in English, refers to a complex network of molecular mechanisms that cells employ to detect and fix damage to their DNA. This damage can arise from various sources, including errors during DNA replication, exposure to environmental mutagens like UV radiation or chemicals, and reactive oxygen species generated during normal cellular metabolism. Without effective DNA repair, accumulating genetic errors can lead to mutations, genomic instability, and ultimately, cell death or diseases such as cancer.
There are several major DNA repair pathways, each specialized for different types of DNA lesions. Base excision
The proper functioning of these DNA repair pathways is essential for maintaining genomic integrity and preventing
