B) Cells will pass through the G1/S checkpoint even if conditions are not ideal for cell division.
Explanation:
The cells will pass through the G1/S checkpoint even if conditions are not ideal for cell division. Because cyclin E is an activator of CdK 2 which stimulates functions of cell entry into S phase.
The most important regulators of Cdk are called cyclin proteins. Cyclines are a family of proteins involved in cell cycle regulation. Cyclines form complexes with cyclin-dependent kinase enzymes (Cdks), activating their kinase function in the latter.
