WebMar 1, 2024 · Nonhomologous end joining leaves evidence of its activity on the genome in the form of deletions flanked with a small number of homologous bases (microhomology). By contrast, no traces are left by the homologous recombination repair pathway. HRR is the most high-fidelity pathway. WebScribd es red social de lectura y publicación más importante del mundo.
