A) a polypeptide of 24 amino acids is formed
B) a polypeptide of 124 amino acids is formed
C) no polypeptides are formed
D) a polypeptide of 25 amino acids is formed.
Correct Answer: A
Solution :
: UAA is one of the three stop codons which do not code for any amino acid. If the codon for 25th amino acid is mutated to UAA then the polypeptide chain will be terminated at that point because tRNA cannot bring next amino acid as UAA is termination codon. So, in this case a polypeptide chain of 24 amino acids will be formed.
