Interphase
What are the three stages of interphase?
G1, S, G2
What are the 4 phases of mitosis?
PMAT
Prophase, Metaphase, Anaphase, Telophase
The cell cycle is....
a. The process from when cells are born to when they die
b. The process from when cells are born to when they divide
c. The process of mitosis
b. The process from when cells are born to when they divide
Cell grows and prepares for DNA REPLICATION
Look at number 5 on your review. What phase of mitosis is pictured?
Metaphase
How many cells are made at the end of mitosis?
2 identical daughter cells
What happens in S phase?
DNA Replication
Look at number 6 on the review. What phase of mitosis is pictured?
Prophase
If a cell normally has 50 chromosomes, how many chromosomes will it have at the end of mitosis?
50 - number of chromosomes stays the same for mitosis!
What happens in G2 phase?
Cell grows and prepares for DNA Replication (Mitosis)
Look at number 7 on the review. What phase of mitosis is pictured?
Telophase
What happens during cytokinesis?
Look at number 9 of your review. What does the number 1 represent? What does number 2 represent?
Both must be right to get the points!!!
1 - Chromatid
2 - Centromere
Look at number 8 on the review. What phase of mitosis do you see?
Anaphase
If a cell is found to have an abnormal number of chromosomes, in what step of the cell cycle would we think an error was made?
ANAPHASE - this is when sister chromatids are pulled apart to make up the chromosomes of the new cells. If an error was made in this phase, we may see the wrong number of chromosomes (it didn't separate correctly).
