Quizplus · Accepted Answer

DNA repair mechanisms occur in both eukaryotes and prokaryotes. These mechanisms are essential for maintaining the integrity of genetic material, and their failure can lead to various diseases or disorders, including cancer. Both prokaryotic and eukaryotic cells have evolved sophisticated DNA repair mechanisms that operate through several complex pathways, such as nucleotide excision repair, base excision repair, and mismatch repair. These pathways involve a series of enzymes and proteins that can detect, remove, and replace damaged or mismatched nucleotides, ensuring that the DNA sequence remains intact and functional.
