How many codons are there in the genetic code?

Explanation:
Codons are triplets of nucleotides in mRNA, and with four possible nucleotides, the number of different triplets is 4 × 4 × 4 = 64. So there are 64 codons in the genetic code. Among these, most codons (61) specify amino acids, while the remaining codons are stop signals to end translation. The reason there are 64 codons but only 20 amino acids is redundancy: multiple codons code for the same amino acid.
