    The codon AUG is

    A)                  ochre                                  

    B)                  amber

    C)                  initiation codon                               

    D)                  termination codon

    Correct Answer: C

    Solution :

                    The codon present in the beginning of a functional gene is called initiation codon. It marks the message for a polypeptide chain. This initiation codon is AUG in most of the cases and it codes for methionine (met) in eukaryotes and for N-formyl methionine (f-met) in prokaryotes. Less often, GUG also serves as initiation codon in bacterial protein synthesis. It is the normal codon for valine.
