In a cell, protein synthesis occurs by the linking together of amino acids. The base sequence of $mRNA$ defines the primary structure of proteins because
- A
Amino acid molecules align directly on the polynucleotide of $mRNA$
- B
It determines the order of alignment of amino acid charged $tRNA$ molecule
- C
There is one to one coding relationship between each base on the $mRNA$ and each amino acid
- D
Each amino acid is defined by a pair of bases on the $mRNA$

Arrangement of $DNA$ has the triplet base sequence $AAC\ GAC\ AGC\ GGC\ ACA\ AAA$. Due to mutation, the first base only got deleted. Then the likely effect of this on the coding of the $DNA$ segment is that
