Cell cycle and mitosis Flashcards
1
Q
What are the three basic stages in the cell cycle?
A
Interphase, mitosis, and cytokinesis
2
Q
What are the four stages of mitosis in order from beginning to end?
A
Prophase, metaphase, anaphase, telophase
3
Q
Is cytokinesis part of mitosis?
A
No
4
Q
What happens in prophase?
A
- Chromatin condenses into chromosomes
- Nucleolus disappears
5
Q
What happens in metaphase?
A
- Nucleus dissolves
- Chromosomes line up along metaphase plate
- Kinetochore fibers attach to centromeres
6
Q
What happens in anaphase?
A
- Chromosomes break at centromeres
- Sister chromatids move to opposite ends of the cell
7
Q
What happens in telophase?
A
- Nuclear membranes reform
- Nucleoli reappear
- Chromosomes unwind into chromatin
- Myosin II and Actin filament ring contracts to cleave cell in two
