C. Mitosis And The Cell Cycle In Eukaryotic Cells Flashcards
Interphase: G1 checkpoint (restriction point)
Go ahead signal for S phase
Interphase:
G1 phase
Recover
Replace any organelle
Grow rapidly: increase size by 2x
Assume metabolism
Interphase:
GO phase
Non dividing phase, normal metabolism
Interphase:
S phase
Synthesis of DNA.
DNA is replicated (make a copy)
Interphase:
G2 phase
Condense chromatin to chromosome
Prepare for mitosis
Replicate the centrosome
Interphase:
G2 checkpoint
Go ahead for mitosis
Interphase
Non dividing time in the cell cycle
Mitosis (M phase)
Division of the nucleus (and contents)
Kinetochore fibers
Attach to kinetochore
Aster fibers
Brace the cell membrane
Non kinetochore fibers
Establish the location of the equator
Centrosome
Microtubular organizing center
Centrioles
Only found in animal cells
Cytokinesis
Division of the cytoplasm to produce daughter cells
Plant cell cytokinesis:
Cell plate
Forms between splitting plant cells
