The standard eukaryotic cell cycle consists of four phases: G1, S, G2, and M phases. There are three phase transitions in a cell cycle: G1/S to initiate DNA synthesis, G2/M to enter mitosis ...

This sequential expression followed the phases of the traditional cell cycle: G0/G1 (the cell grows larger), S (the cell replicates its DNA), and G2/M (the cell prepares for division and then splits).

New research from an international team of plant biologists, led by researchers at the VIB-UGent Center for Plant Systems ...

(C) According to the classical model of cell cycle control, D-type cyclins and CDK4 or CDK6 regulate events in early G1 phase (not shown), cyclin E-CDK2 triggers S phase, cyclin A-CDK2 and cyclin ...
