Identify the wrong statement with regard to Restriction Enzymes.

A Sticky ends can be joined by using \(DNA\) ligases.
B Each restriction enzyme functions by inspecting the length of a \(DNA\) sequence.
C They cut the strand of \(DNA\) at palindromic sites.
D They are useful in genetic engineering.

Verified Solution

Answer & Solution

Correct Answer

(B) Each restriction enzyme functions by inspecting the length of a \(DNA\) sequence.

Step-by-step Solution

Detailed explanation

Each restriction enzyme functions by inspecting the length of a \(DNA\) sequence.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
