Which option gives the wrong target of a restriction enzyme?

Answer and explanation

Correct answer: starch molecule

Restriction enzymes cut DNA at specific recognition sequences. Therefore, a DNA molecule, plasmid DNA, and foreign phage DNA can be their targets. Starch is a polysaccharide, not DNA, so it cannot be a target of a restriction enzyme. Exam tip: associate restriction enzymes with specific DNA sequences, not carbohydrates.
