    Which one of the following triplet codon is known as initiation codon?

    A) UUU  

    B) UAA

    C)  AUG  

    D)  UGA

    Correct Answer: C

    Solution :

     AUG and GUG are called initiation codons because they initiate the polypeptide chain. UAA (Ochre), UAG (Amber) and UGA (Opal) are termination codons. If these codons are present in mRNA, the protein synthesis stops abruptly, whether the protein synthesis is complete or not. UUU codes for phenylalanine.
