Why would it be important to replicate (copy) DNAbefore a cell divides in mitosis or meiosis?
In order for genetic information to be transferred into daughter cells.
In order for the cell to be able to increase in size.
In order for the DNA to be contained in the nucleus.
In order for the cell to re-order the DNA sequencing in the new cells.
What is happening?
Chromosomes are lining up in the middle of the cell.
Sister chromatids are being pulled apart from each other.
The cell is splitting the cytoplasm & forming two new cells.
The DNA condensing into chromosomes.
What is happening?
Chromosomes are splitting apart to move into two different nuclei.
Two cells are fusing together to form one big cell.
Chromosomes are lining up at the middle of the cell before they split apart.
A cell is splitting apart to form two identical cells.
What is happening in this phase?
Chromosomes are being pulled apart into 2 different nuclei.
Chromosomes are lining up at the middle of the cell.
Two cells are fusing together to form one big cell.
A cell is splitting apart to form two identical cells.
Cells of organism must replicate for ___?
growth

Mitosis
How many checkpoints does the cell cycle have?
1
3
5
In general, what is the purpose of a checkpoint in the cell cycle?
To ensure favorable conditions are met before cell division
To ensure apoptosis can occur in health cells
To ensure the cell goes under differentiation
When a healthy cells DNA becomes damaged beyond repair, the cell undergoes which process?
Differentiation
Apoptosis
Meiosis
What might happen if a cell is damaged, but doesn't complete apoptosis and continues to divide?
It will become cancerous
It will differentiate to become a different cell
It will stop at the checkpoints to repair the damage
Any change in the nucleotide sequence of DNA is called...
Error
Translocation
Mutation
