G1
|
growth, normal cell activities; part of interphase
|
|
|
S
|
copy (synthesize) DNA; part of interphase
|
|
|
G2
|
growth, copy other organelles; part of interphase
|
|
|
Prophase I
|
nuclear membrane breaks down, homologous chromosomes pair up to form a tetrad, centrosomes separate, spindle forms and attaches to chromosomes
|
|
|
Metaphase I
|
tetrads line up on metaphase plate
|
|
|
Anaphase I
|
homologous chromosomes are separated by spindle fibers
|
|
|
Telophase I
|
"chromosomes finish movement towards centrosomes, Spindle breaks down, Nuclear membrane reforms
|
|
|
Cytokinesis I
|
division of cytoplasm…now you have 2 cells
|
|
|
Interkinesis
|
cells take a break
|
|
|
Prophase II
|
nuclear membrane breaks down, centrosomes separate, spindle forms and attaches to chromosomes
|
|
|
Metaphase II
|
chromosomes line up on metaphase plate
|
|
|
Anaphase II
|
sister chromatids separate…at this point they are each called chromosomes
|
|
|
Telophase II
|
chromosomes finish movement towards centrosomes, Spindle breaks down, Nuclear membrane reforms
|
|
|
Cytokinesis II
|
division of cytoplasm…now you have 4 cells
