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

• G2

Select all stages of interphase?

• G₁

• S

• G₂

• Mitosis

What part of the cell cycle results in the splitting of the new cells?

• Interphase
• Mitosis
• Metaphase
• Cytokinesis

How many stages are in mitosis?

• 1
• 2
• 3
• 4

Put the following stages of mitosis in order: anaphase, prophase, metaphase, and telophase. 

• prophase, metaphase, telophase, anaphase
• prophase, anaphase, metaphase, telophase
• prophase, metaphase, anaphase, telophase
• prophase, telophase, metaphase, anaphase

Put the following in order: G2, G1, S, mitosis, cytokinesis. 

• G1, G2, S, Mitosis, cytokinesis
• G1, S, G2, Mitosis, cytokinesis
• G1, G2, S, cytokinesis, mitosis
• G1, S, G2, cytokinesis, mitosis

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.
• In order for the cell to be able to increase in size.
• In order for the DNA to be contained in the nucleus.
• In order for the cell to re-order the DNA sequencing in the new cells.
