Targeted genes undergo this process during gene knockout.
The rate of this process is increased at Chi sequences. A protein named for this process cooperates with LexA to initiate the SOS response. The RuvABC family of proteins participates in this process. Mutations in BRCA1, which interacts with Rad51 protein during this process, lead to high rates of breast cancer. Cre proteins recognize loxP sites and initiate this process to occur. If the replication fork collapses, then this process involves strand invasion, branch migration, and then the resolution of the tetrahedral Holliday junction, all designed to repair the DNA. Targeted genes undergo this process during gene knockout. This process occurs at a chiasma during prophase I of meiosis. For 10 points, name this mechanism by which DNA strands exchange nucleotides, such as during crossover.
The rate of this process is increased at Chi sequences. A protein named for this process cooperates with LexA to initiate the SOS response.
homologous recombination [or chromosomal crossover before it is read; or crossing over before crossover is read; prompt on DNA repair]
