Solution

The correct option is E Arg and stop codon
The sequence of mRNA is complementary to that of the DNA template strand. Hence, the mRNA of given DNA strand will have the following sequence: 3’CGC UGU AUG UGA 5’. Hence, the first and last amino acid will be arginine (CGC) and stop codon (UGA).
Therefore, the correct answer is option C.
