|
Genetic material appears as chromotin
|
interphase
|
|
|
asters extend from centrioles
|
prophase 1
|
|
|
nuclear envelope breaks down
|
prophase II
|
|
|
chromosomes cluster at center of cell with the centromeres lined up exactly on the center of the spindle
|
metaphase
|
|
|
the centromeres break, and each chromatid becomes one of two identicle, individual chromosomes, 1 per each daughter cell
|
anaphase
|
|
|
this resembles prophase in reverse as soon as teh chromosomes stop moving
|
telophase
|
|
|
Nucleous is visible
|
interphase
|
|
|
chromatin condenses into chromosomes
|
prophase I
|
|
|
Mitotic spindles interact with chromosomes
|
prophase II
|
|
|
This forms what is called the metaphase plate
|
Metaphase
|
|
|
Kinetichores pull the new chromosomes towards teh respective poles, while the polar microtubles continue to push each other apart, elongating the cell
|
anaphase
|
|
|
Chromosomes unwind into chromatin
|
Telophase
|
|
|
Nuclear envelope is visible
|
Interphase
|
|
|
EAch chromosome consists of two identicle sister chromaides
|
prophase I
|
|
|
The microtubules towards the outer portion of the cell (polar microtubules) push agains each other while the microtubules attached to the chromotids (kinetochores) pull the siter chromatids to the center of the dividing cell
|
prophase II
|
|
|
This stage of mitosis is recognized by the v-shape of the new chromosomes as they are being pulled towards teh poles by spindle fibers
|
anaphase
|
|
|
A new nuclear envelope forms around the chromatin
|
Telophase
|
|
|
To prepare for division the DNA replicates during the Sphase and the centrioles replicate during the G2 phase
|
Interphase
|
|
|
The chromatids are held together by a centromere
|
Prophase I
|
|
|
Nucleoli reappear
|
Telophase
|
|
|
Nucleoli disappear
|
Prophase I
|
|
|
Spindles disappear
|
Telophase
|
|
|
The newly replicated centrioles migrate away from each other and will begin to form the mitotic spindles
|
Prophase I
|
|
|
Cytokinesis (division of the cytoplasm): a ring of actin filaments squeeze the two sister cells apart
|
Telophase
|
|
|
These spindles act to push the two pair of centrioles to opposite sides of the cell.
|
Prophase I
|
