What is most of the cell cycle made up of?
100
Prophase
What is the first and longest stage of mitosis?
100
Mutations,more changes in segments of DNA that code for production of proteins, including those that regulate the cycle.
What is cancer caused by?

What is a stem cell?
200
The cell membrane
What must all substances pass through to go into and out of the cell?
200
The cell grows, performs normal cell functions, and copies its DNA in preparation for cell division.

Carcinogens
What are substances that are known to cause cancer called?
300
They are created after fertilization, when the fertilized egg divides to create 100-150 stem cells.
How are embryonic stem cells created?
400
You multiply the length times width times then number of sides.
How is the surface area calculated?
400
The cell copies its DNA.
What is S stage of the cell cycle?
