“DNA did not magically know there was a cut.”
DNA holds the instructions but doesn't decide on its own — a signal picks the right gene, a copier makes an RNA work-order, and that builds a protein. Pick a scene below, then drag to spin, press Run the signal, and tap any part to learn its name.
DNA did not magically know there was a cut. The cell received signals, and those signals turned the right genes on. Press play to watch all 8 steps.
Pick a signal, press Send signal, and watch the cell decide whether to switch a gene on — one step at a time. Try it with the gene baseline ON (open DNA) and OFF (packed DNA) to see what changes.
Open chromatin — the gene is reachable. Pick a signal and press Send signal.
