Interphase
What are the 3 sub-phases of interphase?
G1, S, G2
What happens during metaphase?
The mitotic spindle lines up the chromosomes in the equator
Is cytokinesis the longest stage, shortest stage, or neither in the cell cycle?
The shortest stage
Where are checkpoints located?
Checkpoints are located at the end of each phase and sub-phase
Why do different cells divide faster than others?
Cells have different needs and jobs
What is the job of the sub-phase G1?
It carries out normal cell functions and prepares to replicate DNA
What are the 4 phases in mitosis?
Prophase, metaphase, anaphase, telophase
When does cytokinesis occur?
After mitosis (last)
What do checkpoints look for?
Checkpoint look for damage or errors in the DNA
What are the 3 reasons cells divide?
Cells divide to be able to grow, reproduce, and replace dead cells
What is the job of the sub-phase G2?
The cell grows and makes special proteins for mitosis
What happens in prophase?
Chromosomes condense, nuclear envelope disappears, centrioles move to opposite sides of the cell, and spindle fiber attach to chromosomes
What is the definition of cytokinesis?
The division of the cytoplasm
What happens to the DNA that is unable to grow, after it went through the G1 checkpoint?
It enters the GO phase
Do all cells take the same amount of time on the cell cycle? Why?
No, cells are not all the same, and have different traits
What is the job of the sub-phase S?
What happens during anaphase?
The sister chromatids separate
What happens during cytokinesis in a plant cell?
A new cell plate forms (cell wall)
What is the main job of checkpoints?
Checkpoints are there so that DNA does not move on with errors or damage
Why do skin cells divide more frequently?
Skin cells are constantly undergoing mitosis so that they can replace the dead skin cells
What is the overall job of interphase?
The cell grows, carries out normal cell functions, and replicates DNA for the next stage
What is the definition of mitosis
The division of the cells nucleus and chromosomes
What happens during cytokinesis in an animal cell?
The cell pinches inward at the middle and forms a cleavage furrow
What happens if a checkpoint fails?
It means the DNA has damage and it can lead to unhealthy cells, and even cancer
Why does a skin cell divide?
A skin cell divides in order to maintain a protective barrier that protects us from infection
