Question
In the genetic dictionary, there are 64 codons as
Options
A.64 amino acids are to be coded
B.64 types of tRNAs are present
C.there are 44 nonsense codons and 20 sense codons
D.genetic code is triplet
Solution
It has been found that a sequence of 3 consecutive bases in a DNA molecule codes for one specific amino acid. So genetic code is a triplet code and there are 64 triplets which are called codons (4 × 4 × 4 = 64) of nitrogen bases for protein synthesis.
