Mitosis Flashcards
1
Q
What are the five steps of mitosis?
A
prophase, prometaphase, metaphase, anaphase, telophase
2
Q
What occurs in prophase?
A
- Chromosomes condense
- spindle apparatus begins to form
3
Q
What occurs in pro metaphase?
A
- nuclear envelope breaks down
- microtubules attach to kinetocore
- chromosomes begin to move to the centre of cell
4
Q
What occurs in metaphase?
A
- chromosomes are moved to the middle of the cell by the microtubules
5
Q
What occurs in anaphase?
A
- sister chromatids separate and are pulled to opposite poles
6
Q
What occurs in telophase?
A
- daughter chromosomes fully separate
- nuclear envelope reforms
- spindle fibres disappear and chromosomes recondense
7
Q
What occurs in cytokinesis?
A
myosin ring causes the plasma membrane to begin pinching in, two daughter cells form
