What is the cell cycle?
The process cells go through that may lead to division.
Which types of cells use the cell cycle and mitosis to reproduce?
eukaryotic cells
What is the cell theory?
Cells are the basic unit of life; Cells come from other cells; All living things are made of cells.
What process do prokaryotes use to copy their cells?
binary fission
What type of reproduction is mitosis/cytokinesis?
asexual reproduction

Why do cells divide? (4 reasons for mitosis)
repair, reproduction, growth, regeneration
What are the stages of interphase (in order in which they occur) and what happens during each phase?
G1- Growth and organelle reproduction, S- DNA is copied, G2- Growth and preparations for division
What is the longest phase of the cell cycle?
Interphase
What is M phase of the cell cycle and what occurs during this phase?
mitosis and cytokinesis- division of the nucleus and cytoplasm
How it mitosis different from cytokinesis?
Mitosis is the division of the nucleus and cytokinesis is the division of the cytoplasm.
How are cancer cells different from normal cells?
They do not follow the rules for the cell cycle and divide out of control.
What are the internal factors (proteins) called that help regulate the cell cycle?
cyclins
What is a carcinogen?
a factor that causes cancer
Tobacco is an example of a carcinogen. Provide two additional examples.
Answers may vary.
Chemotherapy drugs often cause people to lose their hair, explain why this happens?
Chemotherapy drugs damage all cells that are quick-dividing, not just the cancer cells that divide out of control.
