cell cycle in animals Flashcards
1
Q
g2 interphase
A
duplicated centrosomes
2
Q
prophase
A
- condensed chromatin
- nucleoli disappears
- chromatids join with cohesins and centromere
- mitotic spindle begins forming
- centrosomes move away
3
Q
prometaphase
A
- nuclear envelope fragments
- kinetochore forms
- microtubules attach to kinetochores
- nonkinetochore microtubules interact
4
Q
metaphase
A
-centrosomes at opposite ends
-metaphase plate- chromosomes align
-
5
Q
anaphase
A
- cohesions cleave
- chromatids split
- centromeres (chromosomes) move toward the opposite ends
- cell elongates when non kinetochore microtubules lengthen
6
Q
telophase
A
- nuclear envelope
- nucleoli
- un-condense chromosomes
7
Q
cytokinesis
A
cleavage furrow - pinched in 2
