What is the period between cell divisions?
interphase
100
What is the first phase of mitosis?
prophase
100
Name the 3 phases that make up interphase.
G1, S, G2
100
Name the protein that regulates the cell cycle.
Cyclin
100
List the correct order of phases in mitosis AND explain what happens in each phase.
1. Prophase - chromosomes pair up 2. Metaphase - chromosomes line up in the middle 3. Anaphase - Chromosomes split and are pulled to opposite ends of the cell. 4. Telophase - nuclear envelope starts to reform, chromosomes gather in the soon to be nucleus.

the chromosomes are pulled part to opposite ends of the cell.
300
In which phase of the cell cycle does DNA synthesis take place?
S Phase
300
Proteins that respond to events outside the cell are called?
External Regulators
400
Define the cell cycle.
A series of events that cells go through as they grow and divide.
400
