Solution

The correct option is C A polypeptide of 24 amino acids will be formed
A gene encoding a polypeptide of 50 amino acids, if 25th codon (UAU) is mutated to UAA, then the polypeptide forming would stop because UAA is a termination codon which will stop the polypeptide synthesis. Thus, the resultant polypeptide will have 24 amino acids.
