The master switch: how a cell chooses its fate
How this session lines up with the PLTW curriculum and the WebXam for each class it touches, including the vocabulary, concepts, and skills you share.
The classes below may be taught in different terms. This research track runs all year with HOSA, so a connection means the ideas line up, not that the class meets this week.
HBS examines how cells specialize into the body's tissues.
072040 Human Anatomy and Physiology
Domain: Human Body Form, Function, and Pathophysiology
HBS's tissue work depends on the fate decisions this session unpacks.
GenD covers gene regulation, how genes are turned on and off.
072130 Genetics of Disease
Domain: Molecular and Genetic Technology
The master switch is a transcription factor, the same gene-regulation idea GenD teaches.
