Mitosis Flashcards
1
Q
Stages of Mitosis
A
Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
2
Q
What happens in Interphase?
A
G1 - cell grows
S - DNA synthesis
G2 - cell grows
3
Q
What happens in Prophase?
A
- Nuclear envelope breaks down.
-Nucleolus disappears
-Chromosomes coil more tightly - Chromosomes become shorter and fatter
- centrioles move to opposite poles of cell
-microtubules form the mitosis spindle between the centrioles.
4
Q
What happens in Metaphase?
A
- Chromosomes line up along equator of cell - they are maximally condensed
- they are attached to the spindle by the centromere
5
Q
What happens in anaphase?
A
- chromosomes break into two chromatids - separate at the centromere
-spindles contract + pull chromatids to poles of cell.
6
Q
What happens in telophase?
A
- chromatids reach poles and begin to decondense
- nuclear envelope reforms
- cytoplasm splits
7
Q
How many daughter cells does mitosis produce?
