Summary Introduction

To review:

“Doublet code” coding for one amino acid would be sufficient or not.

Introduction:

RNA (ribonucleic acid) refers to a polymeric molecule, which is essential to perform different biological roles in regulation, expression of the genes, decoding, and coding. In this, four nucleotides uracil, cytosine, adenine, and guanine (U, C, A, and G) produce three-letter codons that specify 20 different amino acids.
