Cell Cycle

Why is the Cell Cycle often represented as a circle?

• Because it is easy to draw

• Because cell cycles has a distinct beginning and end point

• to highlight the checkpoints

• to show that it repeats over and over

During which stage of the cell cycle does the nucleus divide?

• interphase

• mitosis

• endocytosis

• cytokinesis

Which statement below desribes the events during G2 of Interphase?

• The cell grows, develops, and makes new proteins

• The DNA replicates to form a new set of identical chromosomes

• The cell grows, makes new organelles, and prepares for mitosis

• the nucleolus disappears and the nuclear envelope disintegrates

Which stage of the cell cycle is MOST critical for ensuring that daughter cells are identical?

• G1

• S

• Prophase

• Mitosis

• G₁

• Cytokinesis

• S

_____ is the uncontrolled growth of cells, often resulting in a tumor or mass of abnormal cells

If you look at a cell under a microscope, which phase is it MOST likely to be in?

• Cytokinesis

• M phase

• Interphase
