- somatic cell replication
1. prophase
2. metaphase
3. anaphase
4. telophase |
|
|
Term
|
Definition
- first phase of mitosis
- centrosomes position themselves on either side of nucleus
- nuclear membrane dissipates |
|
|
Term
|
Definition
- second phase of mitosis
- duplicated chromosomes align in the center of the cell
- centrosomes attach themselves to the chromosomes and prepare to separate them |
|
|
Term
|
Definition
- two duplicated chromosomes are pulled apart by centrosomes
- chromosomes are moved to separate ends of the cell |
|
|
Term
|
Definition
- final stage of mitosis
- components of a new cell begin to appear
- two new nucleus structures are formed by building a nuclear membrane around the two new groups of duplicated chromosomes
- still one cell |
|
|
Term
|
Definition
- stage after mitosis
- cell divides to form two identical cells |
|
|
Term
|
Definition
- gamete production
1. Prophase
2. Metaphase
3. Anaphase
4. Telophase |
|
|
Term
|
Definition
- similar to mitosis except duplicated chromosomes align with the homologous other chromosomes (one from each parent) and get tangled up: CROSSOVER
- while tangled up in crossover, chromosomes exchange genetic info: RECOMBINATION |
|
|
Term
|
Definition
| - like mitosis the chromosomes line up |
|
|
Term
|
Definition
- similar to mitosis
- except they separate as pairs, each with a new combo of genetic material |
|
|
Term
|
Definition
| - 2 new nuclear envelopes |
|
|
Term
|
Definition
| - 2 new cells w/23 new unique duplicated chromosomes |
|
|
Term
|
Definition
- no dna replication
- aim to separate the duplicated chromosomes |
|
|
Term
| Meiosis 2: Metaphase, Anaphase, Telophase, Cyto |
|
Definition
- same as meiosis 1
- end result: four cells each w/23 new chrosomes: GAMETES |
