Vedclass · Answer

(D) The transition from the $G_1$ phase to the $S$ phase in the cell cycle is a critical checkpoint. This transition is primarily regulated by the formation of a complex between $G_1$ cyclins and cyclin-dependent kinases (specifically cdc$2$ kinase or its homologs). These complexes phosphorylate target proteins that initiate $DNA$ replication,thereby allowing the cell to progress from the $G_1$ phase into the $S$ phase.
