9 Cards in this Set
- Front
- Back
|
G1
|
Gap 1, growth, production of cytoplasmic organelles, preparation for chromosome duplication (synthesizes DNA/histones)
|
|
|
S
|
DNA replication, centrosome replication, chromosome replication, cont. growth
|
|
|
G2
|
continued growth, prep for M phase - now 2 centrosomes present
|
|
|
Prophase
|
start of mitotic spindle formation (2 types of microtubules), start of chromosome condensation
|
|
|
Prometaphase
|
nuclear envelope fragments, kinetochore forms at centromere, microtubules attach to kinetochores
|
|
|
Metaphase
|
condensed chromosomes line up at metaphase plate, each chromosome has 2 sister chromatids
|
|
|
Anaphase
|
each centromere splits, sister chromatids move to opposite poles, kinetochore microtubules shorten, causing movement
|
|
|
Telophase
|
daughter nuclei form, chromosomes "decondense"
|
|
|
Cytokinesis
|
begins in telophase, regarded as separate step, clevage furrow in animals, cell plate in plants, 2 separate cells result- exactly identical in mitosis
