In genetic code, 61 codons code for 20 different types of amino acids. This is called

A collinearity
B commaless
C degeneracу
D nonambiguity

Verified Solution

Answer & Solution

Correct Answer

(C) degeneracу

Step-by-step Solution

Detailed explanation

(C) degeneracу,
In the genetic code, the fact that 61 codons code for only 20 different amino acids is known as degeneracy. This means that multiple codons can specify the same amino acid, which provides a level of redundancy and helps protect against mutations.

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.
