Explanation

Yes, it is the correct answer. A is correct whereas R is incorrect Zinc-finger nucleases are artificial restriction enzymes obtained by fusing a zinc finger DNA-binding domain to a DNA-cleavage domain. The DNA-binding domains of individual ZFNs typically contain between three and six individual zinc finger repeats and can each recognize between 9 and 18 base pairs.
