Cell Cycle Review

What does NOT happen during interphase?

• growth
• DNA replication 
• obtaining nutrients
• cell divison

Cytokinesis is a phase of mitosis. 

• True
• False 

Cells spend the majority of their lives in

• Interphase
• Mitosis
• Synthesis 
• Gap 2

Cells of organisms must go through cell division for?

• growth

• repair of damaged cells

• replacement of dying cells.

• All of these

DNA is replicated during ______ of the cell cycle.

• G1

• S

• G2

• G0

What is cytokinesis?

• This is when two cells merge together to make one giant cell.
• The stage where chromosomes migrate to the opposite ends of the cell. 
• The stage of the cell cycle where the rest of the cell divides after mitosis is complete.
• The stage in which DNA condenses into chromosomes.

What occurs during G1?

• Checkpoint after S phase
• Chromosomes line up at the equator.
• The cell grows and develops.
• Spindle fibers separate chromosomes to opposite poles of the cell. 

During most of interphase, DNA is found in a relaxed form called

• chromosome

• centromere

• centriole

• chromatin

During mitosis, DNA is found in the condensed form called a

• chromosome

• centromere

• centriole

• chromatin

In prophase of mitosis, chromosomes

• form and the nuclear envelope disappears.

• are pulled toward opposite ends of the cell.

• chromosomes line up along the equator of the cell

• chromosomes begin to decondense and the two new nuclei begin to form.
