Mitosis Flashcards
1
Q
Anaphase
A
- Separase enzyme splits the proteins that hold together the sister chromatids
- daughter chromosomes are pulled to opposite sides
2
Q
Prometaphase
A
-nuclear envelope breaks, freeing the chromosomes from the nucleus
- centrosomes reach opposite poles
Chromosomes finish condensing
3
Q
Prophase
A
- Chromatin begins to condense
- centrosomes move to opposite sides
4
Q
Telophase
A
- DNA unwinds and a new nuclear membrane forms
- any remaining spindle microtubules are depolymerized
5
Q
Cytokinesis
A
- Splitting of the cytoplasm
- microfilaments pinches two daughter cells like a belt
- cleavage is formed by myosin and actin
6
Q
Interphase(G2)
A
- Occurs before mitosis
- DNA replicates
- cell makes a second centrosome
7
Q
Metaphase
A
- Chromosomes line up in the middle of the cell (equator)
- confirms that there is a microtubule attached to every kinetochore
