Interactive genetic code reference
CodonTable
Standard Genetic Code Chart with a cleaner, faster way to explore RNA and DNA translation
A codon table maps every three‑nucleotide codon in mRNA to an amino acid or stop signal. Use the interactive table to search by codon or amino acid name and compare DNA (T) vs RNA (U).
