A molecule that can act as a genetic material must fulfill the traits given below, except

A it should be able to express itself in the form of ‘Mendelian characters’
B it should be able to generate its replica
C it should be unstable structurally and chemically
D it should provide the scope for slow changes that are required for evolution.

Verified Solution

Answer & Solution

Correct Answer

(C) it should be unstable structurally and chemically

Step-by-step Solution

Detailed explanation

(c) : Genetic material should be structurally and chemically stable otherwise its expression will change and leading to loss of several metabolic functions, etc.

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.
