Answer & Solution

Correct Answer

(A) ઇન્સ્યુલિન

Step-by-step Solution

Detailed explanation

(a) : The recombinant \(DNA\) technological processes have made great impact in the area of health care by mass production of safe and more effective therapeutic drugs. In \(1983\), Eli Lily, an American company, first prepared two \(DNA\) sequences corresponding to \(A\) and \(B\) chains of human insulin and introduced them in plasmids of Escherichia coli to produce insulin chains. Chains \(A\) and \(B\) were produced separately, extracted and combined by creating disulfide bonds to form human insulin (humulin).

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.
