The Cell Cycle
G1, S, and G2 are all apart of this phase.
Interphase
Interphase is composed of these three phases.
G1, S, and G2
Correctly order the four phases of mitosis
Prophase, metaphase, anaphase, telophase.
Genetic information is organized into packages of DNA called
Chromosomes.
The M phase consists of these two stages.
Mitosis and cytokinesis.
Cells spend the most time in this phase.
G1.
Sister chromatids separate in this phase of mitosis.
Anaphase.
In comparison to cancer cells, normal cells spend ______ time completing the cell cycle.
more
The cytoplasm divides during which part of the cell cycle?
Cytokinesis
If a cell is not the correct size, there was likely an issue in this stage of the cell cycle.
G1
What happens in metaphase?
If a cancer cell is deemed to have too much DNA at the G2 checkpoint, it would continue to go through the cell cycle. What would happen if this same situation happened to a normal cell?
The normal cell would undergo apoptosis and wouldn't continue to go through the cell cycle.
Explain how the parent cell "disappears" at the end of the cell cycle.
The parent cell splits into two cells, so the original cell no longer exists.
During these two stages, the cell has double the amount of genetic information.
S and G2
The nuclear membrane reforms and chromosomes decondense during this phase of mitosis.
Telophase.
A cell has 46 chromosomes. It goes through mitosis. How many chromosomes will each daughter cell have?
46
What two stages compose the M Phase?
Mitosis and cytokinesis.
Organelles are duplicated in this stage of interphase.
G2.
If a cell underwent the cell cycle but did NOT undergo cytokinesis, how many nuclei would be in the cell?
2.
If a normal cell fails to pass the G1 checkpoint because it is too small, it would undergo apoptosis. What would happen if a cancer cell fails to pass the G1 checkpoint?
It would continue to go through the cell cycle (and cause more problems).
