In precise genome editing. site-specific DNA double-strand breaks (DSBs) induced by the CRISPR/Cas9 system are repaired via homology-directed repair (HDR) using exogenous donor DNA templates. However. the low efficiency of HDR-mediated genome editing is a barrier to widespread use. https://www.ngetikin.com/great-deal-Soderhamn-Footstool-Cover-great-pick/
