    You are a studying the progression of cells through the cell cycle. You are particularly interested in the role of the APC, which in a ubiquitin E3 ligase, in the control of the metaphase cyclin (cyclin B) and the timing of events. To look at this you start by synchronizing your cells in G1 and examining the levels of Cyclin B over time. The APC usually works on cyclin B during anaphase. RBX57 is a substrate for Cylcin B/CDK2. Given...
