A nucleus-to-ribosome pathway transcribes a short DNA coding example, exports the mRNA and advances a ribosome through AUG GCU UUU GGA UAA. tRNAs deliver amino acids and the chain stops at UAA.
• 3D scene parts: Nucleus and DNA template; mrna and nuclear pore; ribosome subunits; trna adaptors; nascent peptide. • Controls: Transcription duration (2–10 playback s); Translation dwell per codon (0.5–3 playback s); Block mRNA export. • Live readouts: Transcribed message (%); Translated codons; Peptide residues; Released peptide (0/1). • Guided experiments: Block nuclear export; Slower translation. • Four tabs (visual laboratory, curves and measurements, experiments, learn and assess), a model-verification run, a timestamped event log and a trial report.
mRNA: 5′ AUG GCU UUU GGA UAA 3′ Peptide: Met–Ala–Phe–Gly UAA is a stop codon; it does not encode an amino acid.
Molecular geometry, organelle dimensions and animation time are enlarged and illustrative. Colors identify structures rather than natural tissue color. This is a conceptual teaching model, not a cell physiology predictor. Rates are playback times, not biochemical rates. Initiation, splicing, ribosomal A/P/E dynamics and peptide folding are represented conceptually. Try the preset experiments, then compare the live readouts with the equations.
No. Geometry is enlarged and time is a teaching playback scale.
No, it is a stop codon.
