NEET · Biology · STD 12 - 5. molecular basis of inheritance

The first phase of translation is

A Recognition of an anti\(-\)codon
B Binding of \(mRNA\) to ribosome
C Recognition of \(DNA\) molecule
D Aminoacylation of \(tRNA\)

Verified Solution

Answer & Solution

Correct Answer

(D) Aminoacylation of \(tRNA\)

Step-by-step Solution

Detailed explanation

Aminoacylation of \(tRNA\)

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.
