विकल्प

• there are 64 amino acids to be coded

• the genetic code is triplet

• there are 64 types of tRNA with different anticodons

• 20 codon specify 20 amino acids and remaining codons are meaningless

Answer 1

There are 64 codons in the dictionary of genetic code because the genetic code is triplet.

Explanation:

The genetic code is in triplets. Since there are four possible nucleotides (A, T, G, and C), and each codon has three bases/nucleotides, there are a total of 4³ = 64 possible codons.
