Protein Synthesis: Transcription + Translation
受眾: High School類別: Biology
簡介
A two-phase animation of the central dogma. Phase 1 shows transcription inside the nucleus: DNA unzips and mRNA is synthesized. Phase 2 shows translation at the ribosome: tRNA delivers amino acids matching mRNA codons and the protein chain elongates.

Protein Synthesis: Transcription + Translation
Description
A two-phase animation of the central dogma. Phase 1 shows transcription inside the nucleus: DNA unzips and mRNA is synthesized. Phase 2 shows translation at the ribosome: tRNA delivers amino acids matching mRNA codons and the protein chain elongates.
Phases
| # | Phase Name | Duration | Description |
|---|---|---|---|
| 1 | Overview | 3s | Central dogma equation fades in: DNA → mRNA → Protein |
| 2 | Transcription Setup | 4s | Nucleus shown, DNA double helix visible inside |
| 3 | DNA Unzips | 5s | DNA strands separate, showing template strand |
| 4 | mRNA Synthesis | 7s | mRNA strand builds alongside DNA, growing codon by codon |
| 5 | mRNA Exits | 3s | mRNA exits the nucleus toward the ribosome |
| 6 | Ribosome Appears | 3s | Ribosome attaches to mRNA |
| 7 | Translation | 10s | tRNAs bring amino acids one by one, peptide chain grows |
| 8 | Protein Complete | 4s | Completed protein chain labeled, ribosome releases |
| 9 | Summary | 3s | Final labels visible |
