In CRISPR genome editing, Cpf1, proved its marked specificity and produced a mutant mouse

As a new tool in CRISPR genome editing, Cpf1 has sparked an explosion of interest for its attributes that differ from Cas9: It requires only a single RNA that CRISPR RNA assembly is simpler; its staggered cleavage patterns may facilitate substituting existing DNA with desired sequences; and it recognizes thymidine-rich DNA sequences, which has been less explored than the guanosine-rich sequences recognized by Cas9. In sum, Cpf1 is expected to broaden the scope of CRISPR genome editing target sit
