5.Molecular Basis of Inheritance
medium
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
A
The first amino acid will be different and all others will be like the earlier polypeptide
B
The polypeptide will have one amino acid less
C
There will be a complete change in the types and sequence of amino acid
D
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.
