You engineer yeast cells that express the M cyclin during S phase by replacing the gene regulatory sequences of the M cyclin gene with those of the S cyclin gene. Keeping on mind that yeast cells have one common Cdk that binds to all cycling, which of the following outcomes is least likely during this experiment? A. S-Cdk targets will be phosphorylated during S phase
B. There will be both M cyclin-Cdk and S cyclin-Cdk complexes in the cell during S phase
C. G1 cyclin-Cdks will be activated earlier in G1.
D. Some substrates that are normally phosphorylated in M phase will now be phosphorylated in S phase.
