Many of the specific functions that are triggered when a cell passes one of the cell cycle checkpoints result from activation of enzymes and other proteins. A common mechanism for this activation is:a) signal transduction.
b) polymerization of tubulin.
c) phosphorylation of specific proteins.
d) ATP synthesis.
