Cell Cycle and Mitosis

What does NOT happen during interphase?

• growth
• DNA replication 
• obtaining nutrients
• cell divison

Cells spend the majority of their lives in

• Interphase
• Mitosis
• Synthesis 
• Gap 2

DNA is replicated during ______ of the cell cycle.

• Gap 1

• Synthesis (S phase)

• Gap 2

• Gap 0

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.
• The cell grows because extra cytoplasm is made.

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

• chromosome

• centromere

• centriole

• chromatin

In metaphase 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.

This process is the programmed death of a cell

• stem cell

• regulation

• apoptosis

• cytocide

In mitosis, the two resulting cells are

• different from the starting cell and identical to each other.
• different from the starting cell and different from each other.
• identical to the starting cell and different from each other.
• identical to the starting cell and identical to each other.
