Cell Cycle and Cancer

In the S stage of interphase....

• The cell grows
• The nucleus divides
• The cell membrane divides
• The DNA is replicated

When a plant cell goes through cytokinesis....

• A cell plate forms dividing the 2 new nuclei.

• The cell membrane pinches off the 2 new cells.

• 4 new cells are formed.

• Sister chromatids are seperated

Which of the following is the correct order for the phases of the cell cycle?

• G1, M, G2, C, S
• S, G1, G2, M, C
• G1, G2, S, M, C
• G1, S, G2, M, C

Why MUST the S phase always occur before the M phase in the cell cycle?

• The cell must have 2 sets of chromosomes in order to complete M phase

• The cell must grow to a certain size before beginning M phase

• The cell must complete all the necessary checkpoints in order to enter M phase

• The cell must begin the process of cytokinesis before beginning the M phase

G1, S, and G2 phases are combined into one long phase called _____________.

• Interphase
• Mitosis
• Cytokinesis
• The cell cycle

Uncontrollable cell growth is known as _____

• Obesity
• Cancer
• Diabetes
• Hepatitis

A cancer causing agent is called a(n)...

• Somatic mutation
• Carcinogen
• Oncogene
• Germline mutation

• Sudden disruption of blood flow to part of the brain.
• Blood filled weak spot.
• Uncontrolled growth and spread of abnormal cells.
