Mitosis steps Flashcards
1
Q
Stages of mitosis?
A
Prophase, metaphase, anaphase and telophase
2
Q
What happens during prophase? pt1
A
DNA condenses into chromosomes each consisting of two sister chromatids
3
Q
What happens during prophase? pt2
A
Nuclear membrane breaks down; spindle microtubules extend from the MTOC by polymerisation and attach to chromosomes via their kinetochores in the centromere region
4
Q
What happens during metaphase?
A
Chromosomes are aligned at the metaphase plate
5
Q
What happens during anaphase?
A
Spindle microtubules shorten by depolymerization and sister chromatids are separated, and as a result the chromosomes are pulled to opposite poles
6
Q
What happens during telophase?
A
The chromosomes decondense and nuclear membranes are formed around them
