Identify the correct pair of codon and its corresponding amino acid.

The arrangement of $DNA$ has the triplet base sequence $AAC\ GAC\ AGC\ GGC\ ACA\ AAA$. Due to a mutation,the first base is deleted. What is the likely effect of this on the coding of the $DNA$ segment?

In $mRNA$,$AUG$ is the initiation codon and $UAA$,$UAG$,and $UGA$ are termination codons; therefore,a polypeptide cannot be synthesized beyond any of these triplets to the end of the $mRNA$. Which one of the following $mRNA$ sequences can be translated completely?
