Cell Cycle
The longest phase of the cell cycle is?
Interphase
What types of cells enter the G0 stage and do not continue to reproduce over a human's lifespan?
brain cells, muscle cells, nerve cells
In this phase of the cell cycle the cytoplasm divides and creates two new cells.
Cytokinesis
What types of cells are created from mitosis?
Gametes
Somatic Cells
Somatic Cells
What is cancer?
uncontrolled cell growth
In what stage of the cell cycle does division of the nucleus occur?
M phase (Mitosis)
What 3 phases of the cell cycle are part of INTERPHASE?
G1, S and G2
This is the first phase of mitosis in which spindle fibers appear and the nuclear envelope breaks down.
Prophase
Why do cells reproduce using mitosis?
To replace and repair old cells
Name two causes of cancer.
chemical exposure, UV light, radiation, genetics
During what stage of the cell cycle does DNA replication (copied) occur?
S phase
The series of events that a cell goes through as they grow and divide is called the _______ ______.
Cell Cycle
This is the fourth stage of mitosis in which two nuclei are present and the nuclear envelope begins to reform.
Telophase
True or False: The daughter cells created from mitosis are identical to the parent cells.
True
A tumor that is localized and not spreading to other areas is called a _________ tumor
benign
During what stage of the cell cycle does the cell prepare for mitosis by doubling in size?
G 2
During this phase of the cell cycle the cell is growing.
G1
What happens during metaphase?
The sister chromatids line up in the middle of the cell
List three types of somatic cells that reproduce using mitosis?
Skin cells, blood cells, hair cells, bone cells
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
This is the name of the stage some cells enter once they have matured, because they will not be reproducing any more
G0
The word that means cancer has spread to other parts of the body
metastasis
