Details, formula, and sources

Formula or tableStandard genetic-code lookup: each in-frame triplet of RNA bases (A / C / G / U) maps to an amino acid or a STOP codon. DNA sequences are translated by replacing T with U before lookup.

Source and editionStandard genetic code (universal). IUPAC-IUB amino-acid one- and three-letter codes.

What governsEstimate only. Readability formulas and similar metrics are derived from a representative population and have known edge-case noise. The classroom teacher governs final text selection, grade placement, and assessment decisions.
