Mitosis / Meiosis Flashcards
1
Q
S phase
A
Prior to Mitosis/Meiosis
DNA replicates
2
Q
Prophase
A
- Chromatin condenses into chromosomes
- Centrioles form and spindle fibers form
- Nuclear envelope breaks down
3
Q
Metaphase
A
- Chromosomes line up on metaphase plate
- Centrioles are attached to spindle fibers
4
Q
Anaphase
A
- Centrioles split
- Sister chromatides are pulled apart
5
Q
Telophase
A
- Cell membrane pinches in half
- Nuclear envelopes reform
- 2 indentical daughters produces
- If diploid cell undergoes mitosis –> 2 dipoloid (2n) cells are produced
- If haploid cell undergoes mitosis –> 2 haploid (n) cells are produced
6
Q
Prophase I
A
- Chromatin condenses into chromosomes
- Centrioles form and spindle fibers form
- Nuclear envelope breaks down
- *Chiasmata forms tetrads and crossing over
7
Q
Metaphase I
A
- Chromosomes pairs line up on metaphase plate
- Centrioles are attached to spindle fibers
8
Q
Anaphase I
A
- *Homologous pairs are pulled apart
9
Q
Telophase (Meiosis)
A
- Cell membrane pinches in half
- Nuclear envelopes reform
- 2 haploid daughter produced
