Which of the APC descriptions is incorrect? A: APC is anaphase-promoting complex. B: APC is a ubiquitin ligase E3. C: The activation of APC eventually leads to the release and activation of the separation enzyme, which in turn leads to the separation of sister chromatids. D: Activated cdc20 binds to APC and inhibits APC activity.
