Cell Cycle
Cell growth and division occurin a regular cycle. This cycle is divided into fourphases: G1, S, G2, and
M. The diagram shows this cycle, along with events that occur in each phase. Follow the prompts
below.

BLUE
v Color the phase in which DNA replication occurs RED.
v Color the phase in which preparation for mitosis
occurs in YELLOW.
v Color the phase in which mitosis and cytokinesis
