The codon UAA serves as a stop signal. Hence, if the polypeptide synthesis halts at the 25th amino acid, a chain containing 24 amino acids will be produced.

1. a) Correct
2. b) Incorrect
3. c) Partially correct
4. d) None of these

Correct answer: a) Correct

Solution

The stop codon UAA signals the termination of translation, and the polypeptide chain formed will have 24 amino acids before the stop codon. Thus, the statement is correct.
