Which option is wrong about restriction enzymes?

Answer and explanation

Correct answer: They are the main enzymes for starch digestion

Restriction enzymes are proteins that recognize particular nucleotide sequences in DNA and cleave the DNA backbone at or near those sites. Because their cutting is sequence-specific, they are essential tools in recombinant-DNA work, where a vector and a desired DNA fragment must be cut in a controlled manner. They do not digest starch; starch digestion is mainly carried out by amylolytic enzymes such as amylase, which act on carbohydrate bonds. Therefore option D is the wrong statement. Options A, B, and C correctly describe the cutting activity, sequence recognition, and biotechnology use of restriction enzymes.
