Full teaching script
- Today: Gene expression and control. Our goal: Explain transcription, translation and regulation.
- Take one idea at a time. Pause after each sentence; ask for repetition whenever you need it.
- DNA is transcribed to mRNA in the nucleus, spliced, then translated at the ribosome, three bases per amino acid. Control happens at every level — transcription factors, methylation, histone acetylation, siRNA — which is why one genome builds two hundred cell types.
- Together: choose one example from the explanation and show how it works. What do you notice?
- Your turn: Trace one gene from promoter to folded protein.
- Reflect: what made sense, and what would you like explained differently?
