Tumor Suppressor Genes, Extended
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Tumor suppressor genes, homed at Bio 0899, reappear as regulation examples: a disabling mutation removes the restraint on division this framework relies on.
Show
The p53 tumor suppressor, per Bio 0899, halts a damaged cell's division; a disabling mutation lets it keep dividing.
Watch for
This entry extends Bio 0899 into this unit's regulation framework, alongside Bio 1339 — it does not relock either term.
