Meiosis Flashcards
1
Q
Interphase 1
A
DNA replicates
2
Q
Prophase 1
A
2nd phase
- chromosomes become visible
- nuclear membrane breaks down
- chromosomes pair up with homologous pair
3
Q
Metaphase 1
A
3rd phase
- chromosomes move and line up along equator
- random assortment of homologous pairs
- spindles from each pole attach to one homologous chromosome
-
4
Q
Anaphase 1
A
4th phase
- homologous chromosomes split and are pulled to poles
- sister chromatids remain intact
5
Q
Telophase 1 and cytokinesis 1
A
- spindle breaks down
- cells separate
- ## nuclear membrane reforms
6
Q
Prophase 2
A
1st phase
- nuclear membrane breaks down again
- new spindles form
7
Q
Metaphase 2
A
2 pond phase
- chromosomes move to equator
- spindles attach to centromere
8
Q
Anaphase 2
A
3rd phase
- chromatids split and move to poles
- now referred to as chromosomes again
9
Q
Telophase 2 and cytokinesis 2
A
- Cytoplasm begins to divide in both cells
- spindles break down
- nuclear membrane reforms
