Does this tool support alternative genetic codes?

No, this translator uses the standard universal genetic code to translate codons into amino acids.

How does the tool handle DNA sequences containing Thymine (T)?

The tool automatically normalizes Thymine (T) to Uracil (U) before performing the translation.

What is an Open Reading Frame (ORF) in the results?

An ORF is a sequence of codons starting with an AUG (Methionine) and ending at a stop codon (UAA, UAG, or UGA).

Can I translate the reverse complement strand?

Yes, you can choose to translate the forward strand, the reverse complement strand, or all six reading frames at once.

How are the amino acids categorized in the composition table?

Residues are grouped and color-coded by their chemical properties: hydrophobic, polar, acidic, basic, and special.

Codon to Amino Acid Translator

Translate a DNA or mRNA sequence into protein using the standard genetic code. Scans all 6 reading frames (forward and reverse complement), marks start (AUG) and stop codons, identifies the longest open reading frames (ORFs), and shows the amino-acid composition with color-coded residue types. Supports T→U normalisation and reverse-complement translation.

What this tool helps you do

A molecular-biology translator for students, pre-meds, and synthetic-biology learners:

Input — paste a DNA or RNA sequence (T and U are both accepted; non-ACGT characters are stripped with a notice).
Strand — translate the forward strand (3 frames), the reverse complement (3 frames), or both (all 6 frames).
Reading frames — each codon is shown next to its amino acid; AUG is flagged as a start (Methionine), and UAA/UAG/UGA as stop codons.
ORF detection — every frame's open reading frames (AUG → stop) are located; the frame with the longest ORF is highlighted as the best.
Composition — the best frame's amino-acid breakdown is tabulated by count and percentage, with residues color-coded by chemical class (hydrophobic / polar / acidic / basic / special).

Uses the standard (universal) genetic code. No external calls — pure lookup.

Longer gene, reverse-complement detection

A sequence whose real ORF lies on the reverse strand; the tool highlights the reverse frame as the best by ORF length.
