G0 or senescent
resting/non-dividing cells
cells in this cycle that divide are somatic
The Cell Cycle
interphase → mitosis
Interphase
bulk time (>90%)
G1
S
G2
G1
Gap1 - cell grows + preps for DNA replication
S
Synthesis - DNA replication
G2
Gap2 - prep for mitosis
Mitosis
divison (PMAT acronym)
PMAT
Prophase, Metaphase, Anaphase, Telophase/Cytokinesis
Prophase
chromatin condenses into distinct chromosomes
special microtubules = spindle fibers that begin to form @ centrioles
Metaphase
spindles attach to protein structures @ centromere = kinetochore
chromosomes line up @ metaphase plate/equator lining up in the cafeteria
Anaphase
spindles begin to shorten and pull sister chromatids apart
once sisters are separated, they are now chromosomes
Telophase/Cytokinesis
nuclear membrane reforms and cytoplasm divided and membrane reforms around 2 cells
Formation of sex cells (gametes)
interphase → meiosis I → meiosis II
