10.2 The Process of Cell Division

10.2 The Process of Cell Division

Key Idea: Describe role of chromosomes in cell division

Chromosomes make it possible to separate DNA precisely during cell division.

​

Before division, cell make an exact copy of their chromosomes.​

10.2 The Process of Cell Division

Multiple Choice

If a cell has 12 chromosomes before cell division, how many chromosomes will each of its daughter cells have after mitosis and cytokinesis?

• 4

• 6

• 12

• 24

Key Idea: Name the main events of the cell cycle

During the cell cycle, a cell grows, prepares for division, and divides to form two daughter cells.

​

Any time a cell is not dividing, it is in interphase​

10.2 The Process of Cell Division

Multiple Choice

The period between cell divisions is called

• interphase

• prophase

• G3 phase

• cytokinesis

Key Idea: Describe what happens during the four phases of mitosis

Prophase - genetic material inside the nucleus condenses

Metaphase - chromosomes line up across the center of the cell

Anaphase - chromosomes separate and move along spindle fibers to opposites ends of the cell

Telophase - chromosomes begin to spread out into a tangle of chromatin​

• Telophase

Multiple Choice

What phase is this cell likely in?

• Prophase

• Metaphase

• Anaphase

• Telophase

Key Idea: Describe the process of cytokinesis

Cytokinesis completes the process of cell division -- it splits one cell into two
