Question:
Which one of the following is NOT a characteristic of genetic code?
Which one of the following is NOT a characteristic of genetic code?
Show Hint
The genetic code is commaless, in triplets, and degenerate, but it is not ambiguous. Each codon specifies a unique amino acid.

- It is commaless.
- It is in triplets.
- It is degenerate.
- It is ambiguous.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the characteristics of genetic code.
The genetic code is commaless (no commas between triplets), is in triplets (codons), and is degenerate (more than one codon can code for the same amino acid). However, it is not ambiguous; each codon codes for a specific amino acid.
Step 2: Analyzing the options.
(A) It is commaless: Correct. The genetic code does not have commas between codons.
(B) It is in triplets: Correct. The genetic code is read in triplets of nucleotides (codons).
(C) It is degenerate: Correct. More than one codon can code for the same amino acid.
(D) It is ambiguous: Incorrect. The genetic code is not ambiguous; each codon specifies only one amino acid.
Step 3: Conclusion.
The correct answer is (D) It is ambiguous, as the genetic code is not ambiguous.
