Vedclass · Answer

(C) The codon $UAU$ codes for the amino acid Tyrosine. $UAA$ is a stop codon (nonsense codon) that does not code for any amino acid and signals the termination of protein synthesis. Since the mutation occurs at the $25^{th}$ position,the translation process will stop after the $24^{th}$ amino acid is incorporated. Therefore,a polypeptide chain consisting of only $24$ amino acids will be formed.

If the $25^{th}$ codon $UAU$ in a polypeptide chain of $50$ amino acids undergoes a mutation to $UAA$,what will be the result?
