This fact sheet is for the video DNA Repair - BER, direct, proofreading, HR, MMR, NHEJ and NER.
DNA can be damaged in a number of ways — see How can DNA become damaged in the cell? — and damage must be corrected for the cell to function correctly.
There are seven ways cells can repair damage to their DNA: direct repair; Base Excision Repair (BER); Nucleotide Excision Repair (NER); DNA proofreading; Mismatch Repair (MMR); Non-homologous end joining (NHEJ) and Homologous recombination repair (HR)
The fact sheet, along with the video, describes the methods and the key terms associated with them.
