Solution

The correct option is D $216$
If DNA made of 4 nucleotide, then due triplet nature of codon .
No. of triplet codon possible = 4³ $\to$ 4x4x4 $\to$ 64
Out of 64 codon, 61 code for 20 amino acids and 3 codon are stop codon.
If DNA made of 6 nucleotide -
No. of triplet codon possible = 6³ $\to$ 6x6x6 $\to$ 216
So, the correct answer is ' 216 '
