Interactive explorer
Translation explorer
Follow standard genetic-code decoding conceptually (not every initiation factor is drawn).
What this explorer teaches
mRNA, ribosome, tRNA, codon/anticodon pairing, and a growing peptide — educational model.
Learning goal: Reinforce start→stop ORF reading before codon-chart drills.
Interactive model
Educational model — simplified for learning. Not medical advice. Features are conceptual and not drawn to molecular scale unless stated.

Guided steps (text)
- Step 1: mRNA
- Step 2: Ribosome
- Step 3: tRNA
- Step 4: Codon / anticodon

How to use this explorer
- Advance with Next / Previous, the step chips, or keyboard ← →.
- On touch devices, tap chips and buttons (minimum comfortable target size).
- If you prefer reduced motion, the site respects
prefers-reduced-motionand jumps between states without animation. - Screen-reader / keyboard users: focus stays on controls; the live region announces the current step.
Scientific notes & limits
Ribosomes read mRNA codons; tRNAs bring amino acids via anticodon pairing; peptides grow until a stop codon. Initiation/elongation/termination factors and alternative genetic codes are beyond this overview. Use Chromatin.net tools for sequence practice with the standard code.

- Translation — Translation is ribosomal synthesis of a polypeptide directed by mRNA codons.
- Codon — A codon is a three-nucleotide mRNA sequence that specifies an amino acid or a translation stop signal.
- tRNA — Transfer RNA (tRNA) delivers amino acids to the ribosome by matching anticodons to mRNA codons.
