Which of the following is NOT a way G1/S cyclin/cdks ensure progression through the cell cycle?
A)inactivate APC via Cdh1 phosphorylation
B)phosphorylate the S phase inhibitor (CKI)
C)activate SCF E3 ligase
D)activate expression of S-phase cyclins

SCF E3 ligase is not directly activated by G1/S cyclin/cdks to ensure progression through the cell cycle. Instead, G1/S cyclin/cdks primarily work by inactivating inhibitors and promoting the transition to S phase through mechanisms like phosphorylation of proteins that inhibit cell cycle progression, not by directly activating SCF E3 ligase.
