Which of the following methods results in no loss of information when repairing a double-stranded DNA break?
Recombination between homologous chromosomes is one of the only methods for repairing double-stranded breaks in DNA without losing information. This method only works, however, if there is an extra copy of the same DNA in the cell (i.e. on a homologous chromosome). Recombination is not possible prior to the S phase of the cell cycle, during which DNA is replicated.
Non-homologous end joining results in the deletion of a few base pairs, which can be problematic if done in the coding region of a gene. Translesion synthesis actually has nothing to do with double-stranded breaks, and refers to a method of accurately synthesizing DNA over mutations (such as thymine dimers) by using specialized polymerases.
