When the NHEJ pathway is inactivated, double-strand breaks can be repaired by a more error-prone pathway called microhomology-mediated end joining (MMEJ). In this pathway, end resection reveals short microhomologies on either side of the break, which are then aligned to guide repair. [8]
A single-stranded break (nick) in DNA can be formed by the hydrolysis and subsequent removal of a phosphate group within the helical backbone. This leads to a different DNA conformation, where a hydrogen bond forms in place of the missing piece of the DNA backbone in order to preserve the structure.
Unrectified lesions may also interfere with polymerase function, induce transcription or replication errors, or halt replication. Notably, pyrimidine dimers contribute to sunburn and melanin production, and are a primary factor in melanoma development in humans.
Automatic bug fixing is made according to a specification of the expected behavior which can be for instance a formal specification or a test suite. [5]A test-suite – the input/output pairs specify the functionality of the program, possibly captured in assertions can be used as a test oracle to drive the search.
