Cell Cycle

The cell cycle begins when a new cell forms from the division of a parent cell.

The Eukaryotic Cell Cycle

Multiple Choice

How do new cells form?

• When the parent cells die.

• From parent cells dividing.

• When parent cells are sick.

• It doesn't

The cell cycle has two main stages:

• interphase (G_1, S, and G₂)

• and cell division (M phase and cytokinesis)

Cell Cycle Stages

Multiple Select

What are the two main stages of the cell cycle?

• anaphase

• cell division

• interphase

• synthesis

• Interphase - the stage where the cell grows and matures.

• Cells spend 90% of their lifetime in interphase.

• Interphase has three phases: G₁ phase, G₂ phase, and S phase.
