From this and other discoveries, including the discovery of the RAD9 gene with former postdoc Ted Weinert, Hartwell hypothesized that checkpoints regulate the sequence of events in mitosis.1 His ...

In this role-playing game, students act as cells (healthy and cancerous) and go through the cell cycle, while some students play the roles of checkpoint proteins. This experience deepens their ...
