Cell Cycle and Mitosis Reassess Review

Multiple Choice

The three stages of the cell cycle are __________, mitosis, and

cytokinesis.

• interphase

• anaphase

• metaphase

• prophase

Mitosis

Cell division has two (2) main stages: mitosis & cytokinesis.

​

There are four parts to mitosis:

1. Prophase

2. Metaphase

3. Anaphase

4. Telophase​

Module 4: Cell Cycle & Division

• Prophase: Genetic material condenses &​ chromosomes become visible

• Metaphase: Chromosomes line up down the middle of the cell

• Anaphase: Chromosomes move away from each other

• Telophase: Begin to see 2 distinct cells​

Mitosis

Multiple Choice

What phase is Telephase?

Multiple Choice

What phase is Prophase?

• ​DNA begins to thicken and condense (smaller/compact)

• Centriole pairs/centrosomes begin to migrate to opposite poles, spindle fibers forming between them

• ​Nuclear membrane and nucleolus dissolve

​

​

​Prophase

​

​centrioles

• Centrioles moved to opposite poles​ with stretched out spindle fibers

• Sister chromatids aligned along equatorial plate.

• Spindle apparatus/mitotic spindle fully formed.

  ​

​Remember: the chromosomes are replicated. They are two identical sister chromatids attached to each other

​

​Metaphase

​

​spindle fibers

• ​Spindle fibers shorten and pull apart sister chromatids at the centromore and drag the chromatids to opposite poles

• ​Split sister chromatids become chromosomes

​Anaphase

​

• A nuclear membrane forms around each group of chromosome

• Spindle fibers break apart​

• DNA uncoils/disperses​

• Cleavage furrow forms to separate the cytoplasm​ (plant cell - cell plate)

  ​signals cytokinesis

​

​

​

​Telophase

​

• division of the cytoplasm

• the membrane pinches closed, forming

  a separate cell around each nucleus.​

​

​Cytokinesis

​

• Recreation 2 new daughter cells

• New cells enter

  interphase and begin

  the cycle again.

​

​Cytokinesis

​

4 Checkpoints to prevent compromised cells from continuing to divide:

1. G1 Phase

2. S Phase

3. G2 Phase

4. M Phase

​Occurs at the end of each phase

​Checkpoints

​

G1 Checkpoint:

​

​Checks for healthy DNA and if there are enough resources for division

​Occurs at the end of each phase

​Checkpoints

​

S Phase:

​

​Checking for errors in replicated DNA

​Occurs at the end of each phase

​Checkpoints

​

Multiple Choice

These are important points in the cell cycle that look for errors and stop the process if errors are detected to prevent changed cells

• Checkpoints

• Cell Cycle

• Apoptosis

• Interphase

Multiple Choice

What happens if a checkpoint detects any of the following within a cell: damage to DNA, errors in DNA replication, or incorrect attachment of spindle fibers?

• The process is stopped until these things are repaired or a cell is killed

• The process will stop but the cell will never be killed

• The process continues

• Checkpoints will not check for these things
