What are the two main phases of the cell cycle?
- Synthesis (S Phase)
- Mitosis (M Phase)
In reference to the cell cycle, what does the G phase refer to?
The cell is metabolically growing enzymes or proteins in preparation for DNA synthesis or mitotic division
In reference to the cell cycle, what does the G zero phase refer to?
A state of dormancy where they are not actively proliferating
What cell phase differs in duration time?
G1 can vary from a few hours to several days
What does cell differentiation refer to?
The process by which proliferating cells become specialized
What are the three main categories of cells produced through cell differentiation and proliferation?
- Cells that never or rarely divide
- Cells that continue to proliferate and then die
- Cells produced through proliferation
