The Cell Cycle

Stages of Cell Cycle

100

Cell cytoplasm divides

What is cytokinesis?

200

DNA replicates

What is the S phase?

300

The cell grows and carries out normal activities after division has occurred

What is the G1 phase?

400

The stage that includes G1, S, and G2

What is interphase?

500

Cell preparation for division occurs

What is the G2 phase?

Interphase

100

G1, S, G2

What is are the phases of interphase?

200

Growth and normal cellular functions

What is G1 & G2?

300

What does the S mean in the S phase and what happens in this stage?

S stands for synthesis and the DNA gets duplicated

400

Unreplicated DNA.

What is G1 phase?

500

How do the G1 and G2 checkpoints differ?

G1 checkpoint makes sure the cell is large enough and is healthy enough to go through the cell cycle G2 checkpoint sends out repair enzymes to make sure the DNA strand was copied correctly?

Mitosis

100

Chromosomes are unwinding and become enclosed in the nucleus, and the cell begins to divide

What is telophase?

200

Chromosomes are lined up on the cell's equator

What is metaphase?

300

The cell's chromosomes become visible, the nuclear membrane disappears, and the centrioles move to opposite sides of the cell

What is prophase?

400

Chromatids are pulled apart and become individual chromosomes

What is anaphase?

500

Spindle fibers appear and attach to centromeres

What is prophase?

Errors

100

There is an error in cell growth. So the cell is stuck at a checkpoint.

What is G1 checkpoint?

200

A drug disrupts the forming of spindle fibers. This stops mitosis. The cell can't pass a checkpoint and move on to complete this cell cycle.

What is M phase checkpoint?

300

A mutation occurs in a cell and they can't pass the M phase checkpoint. The cell can never go through this phase.

What is Mitosis?

400

Doesn't occur in Mitosis.

What is replication of DNA or organelle & protein growth.

500

Did not properly replicate their organelles.

What is G1 checkpoint?

Miscellaneous

100

What would happen if the G2 checkpoint was defective?

The cell wouldn't go through mitosis and it the mass would stay the same

200

How are chromatin, chromatid, and chromosomes similar

All strands of DNA

300

If the parent cell has 65 chromosomes, how many chromosomes are in each daughter cell?

65

400

The two phases associated with cell division are...

What are mitosis and cytokinesis?

500

What would happen if cytokinesis was skipped?

No genetics would be passed on the cell would get too large cell would die
