Interphase
The longest phase of the cell cycle is?
Interphase
Why do cells reproduce using mitosis?
To replace and repair old cells
In this phase of the cell cycle the cytoplasm divides and creates two new cells.
Cytokinesis
True or False: p53 is a gene
True
What is cancer?
uncontrolled cell growth
During what phase of the cell cycle does it check itself prior to starting cell division?
G2
True or False: The daughter cells created from mitosis are identical to the parent cells.
True
This is the first phase of mitosis in which spindle fibers appear and the nuclear envelope breaks down.
Prophase
Why do elephants have less rates of cancer despite being long-lived and large animals?
They have multiple copies of p53
A tumor that is localized and not spreading to other areas is called a _________ tumor
benign
During what stage of the cell cycle does DNA replication (copied) occur?
S phase
In what stage of the cell cycle does division of the nucleus occur?
M phase (Mitosis)
This is the fourth stage of mitosis in which two nuclei are present and the nuclear envelope begins to reform.
Telophase
What can cause the p53 gene to stop working correctly?
it picks up mutations during DNA replication and cell division
How does cancer negatively affect nearby cells?
Cancer cells take up space and resources from healthy cells
During this phase of the cell cycle the cell is growing.
G1
What happens during cytokinesis?
the cell divides the cytoplasm and the organelles into two separate daughters cells
What happens during metaphase?
The sister chromatids line up in the middle of the cell
What 3 trends did we see about who tends to get higher rates of cancer?
1) tall people, 2) elderly people, 3)living on the East Coast
A tumor that has spread to other parts of the body is called a _________ tumor
malignant
Put the following stages of the cell cycle in order
G2, S-phase, M-phase, and G1
G1, S, G2 and M
Put the following actions that occur during the cell cycle in order
DNA Replication, Cell Division, Prepares for Mitosis and Cell Grows
Cell Grows, DNA Replication, Cell Prepares for Mitosis and Cell Division
In this phase of mitosis, spindle fibers pull chromosomes to opposite poles of the cell
anaphase
What does p53 do during the cell cycle?
it checks to make sure the cell has the right amount of nutrients, organelles and DNA before letting the cell move onto the next cell cycle phase
The word that means cancer has spread to other parts of the body
metastasis
