What is the Genetic Code?
The genetic code is the set of rules used by living cells to translate genetic information encoded in triplet codons of mRNA into amino acid chains during ribosomal translation.
Formula & Step-by-Step Calculation
3 Nucleotides = 1 Codon = 1 Amino Acid (64 Codons ⟶ 20 Amino Acids + 3 Stops)
Degenerate, non-overlapping universal triplet code.
Worked Step-by-Step Examples
