Cell Cycle & Cancer Exam Part 1

During Interphase the cell will

• perform normal functions

• grow

• copy its DNA

• duplicate its organelles

Match the following

• G₁

• division of nucleus

• G₁, S, G₂

• Interphase

• S

• M Phase

• Mitosis

• DNA Replicates

• Cell Division

• cell growth

Answer explanation

Interphase consists of 3 subphases: G₁, S, and G₂.

Interphase is when the cell is preparing to divide.

M Phase consists of 2 subphases: Mitosis and Cytokinesis

Mitosis will divide up the DNA that is in the nucleus.

In which phase of a cell’s life cycle will the cell have two copies of its DNA?

• Beginning of G₁

• Beginning of S

• End of S

• End of M

Answer explanation

At the end of S phase is when you will find 2 sets of DNA.

S Phase is the synthesis of a second set of DNA.

What is replicated in S phase?

(a)  

Put the stages of the cell cycle in order from Interphase to M Phase

• G₂

• Mitosis

• Cytokinesis

• S

• G₁

Answer explanation

Why do cells divide?

• growth of organism

• repair damaged tissue

• reproduction

  (asexual/sexual)

Answer explanation

Arrange the following levels of hierarchy from smallest to largest

• Organism, Organ, Tissue, Cell, Organelle

• Cell, Tissue, Organ, Organ System, Organism

• Organism, Cell, Tissue, Organ

• Tissue, Cell, Organ, Organism

Answer explanation

An abnormal mass of cancer cells is called a 

• tumor
• cyst
• lesion
• polyp

Which process will create new cells?

• Interphase

• Mitosis

Cancer is a consequence of the disruption of the cell cycle

• True
• False
