G1 Phase
S Phase
G2 Phase
M Phase
Control of Cell Cycle
100
G1 Phase is mostly for these two things.
What is growth and DNA check?
100
During the S phase this occurs.
What is DNA replication?
100
This occurs during the G2 phase.
What is protein synthesis for cell division?
100
This is the dividing of the nucleus.
What is mitosis?
100
These are the signaling proteins received at the plasma membrane.
What are growth factors?
200
This occurs if the DNA is damaged.
What is apoptosis?
200
Each double helix of DNA in a chromosome is called this.
What is a chromatid?
200
It forms proteins that are used to make these.
What are microtubules?
200
The dividing cell in mitosis.
What is a parent cell?
200
These are the family of internal signaling proteins that increase and decrease as the cell cycle continues.
What is a cyclin?
300
As cells grow in this phase, these organelles increase.
What is ribosomes and mitochondria?
300
These are two identical chromatids.
What are sister chromatids?
300
This occurs at the G2 checkpoint.
What is a check for correctly synthesized DNA?
300
In this phase the chromatin have condensed and the chromosomes are visible.
What is the prophase phase?
300
This protein is responsible for interpreting growth and signals and nutrient availability signals.
What is RB?
400
This stage occurs when no preparations are made for cell division and the cell only performs normal processes.
What is the G0 phase?
400
This is what the S in “S phase” stands for.
What is synthesis?
400
This is rapidly produced during this phase.
What are proteins?
400
These are the three functions for mitosis.
What are asexual reproduction, growth, and repair?
400
It is in these cells that p53 stops the cycle at G1 checkpoint if DNA is damaged.
What are mammalian cells?
500
These are example of cells that go into the G0 phase.
What are nerve and muscle cells?
500
The cell can transition from this phase once this has occurred.
What is the formation of twin chromatids and DNA replication?
500
The G2 checkpoint determines if the cell can go into this phase.
What is M phase?
500
An imaginary plane that is perpendicular and passes through the cell that indicates the future axis of cell division.
What is a metaphase plate?
500
The enzymes that bring about apoptosis and are always present in the cell are called this.
What are caspases?
