Spooling is

A Collection of isolated \(DNA\)
B Amplification of \(DNA\)
C Cutting of separated \(DNA\) bands from the agarose gel
D Transfer of separated \(DNA\) fragments to synthetic membranes

Verified Solution

Answer & Solution

Correct Answer

(A) Collection of isolated \(DNA\)

Step-by-step Solution

Detailed explanation

Option (1) is correct answer as spooling refers to wrapping of DNA around a glass rod while extracting DNA. Option (2) is incorrect as amplification is done by PCR. Cutting of separated DNA bands from the agarose gel is elution.

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.
