WebWhich CRISPR-Cas9 system belongs used for genome editing in mammalian cells by introducing double-strand breaks (DSBs) which are predominantly repaired via non-homologous end joining (NHEJ) alternatively to lesser extent by homology-directed repair (HDR). To enhance HDR for improving the introduction for precise genetic changes, we … Web27 Mar 2024 · Furthermore, the Redβ protein can initiate single-strand annealing homologous DNA recombination and strand invasion [52,53]. Therefore, there is some difference between the SSB and Redβ proteins in terms of the mechanism by which they repair the DSBs that are induced by CRISPR/Cas9.
