DNAreparaatioita
DNAreparaatioita, known in English as DNA repair, refers to a collection of cellular mechanisms that function to counteract DNA damage. DNA is constantly exposed to various damaging agents, including environmental mutagens like UV radiation and chemicals, as well as endogenous factors like reactive oxygen species. If left unrepaired, this damage can lead to mutations, which can have severe consequences for the cell and the organism, including cancer and premature aging.
There are several major pathways for DNA repair. Nucleotide excision repair (NER) is a versatile mechanism that
These repair systems are crucial for maintaining genomic stability and preventing disease. Defects in DNA repair
