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

The first amino acid will be different and all others will be like the earlier polypeptide

The polypeptide will have one amino acid less

There will be a complete change in the types and sequence of amino acid

There will be no change in the polypeptide chain formed

(AIIMS-1980)

Solution

(b) On the deletion of first base of triplat, the polypeptide will have one amino acid less in the $DNA$ segment because each triplet representing one amino acid of a polypeptide.
