Following statements describe the characteristics of the enzyme Restriction endonuclease. Identify the Incorrect statement.

A The enzyme cuts \(DNA\) molecule at identified position within the \(DNA\)
B The enzyme binds \(DNA\) at specific sites and cuts only one of the two strands.
C The enzyme cuts the sugar-phosphate backbone at specific sites on each strand.
D The enzyme recognizes a specific palindromic nucleotide sequence in the \(DNA\)

Verified Solution

Answer & Solution

Correct Answer

(B) The enzyme binds \(DNA\) at specific sites and cuts only one of the two strands.

Step-by-step Solution

Detailed explanation

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.
