Interactive explorer
Transcription explorer
See coding/template relationships at a classroom level without implying molecular-scale accuracy.
What this explorer teaches
Conceptual DNA → RNA view with RNA polymerase and transcript — not to scale.
Learning goal: Pair with the transcription worksheet/tool for sequence practice after the conceptual model.
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: DNA template idea
- Step 2: RNA polymerase (conceptual)

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
RNA polymerase synthesizes RNA complementary to a template strand. Classroom models often start from coding/template language. Promoters, enhancers, splicing, and polymerase subtypes are not fully represented — and nothing here is to molecular scale.
