prophase
What starts to dissolve in this Phase
The nucleoli
what fragments in this phase
nuclear envelope
During metaphase, chromosomes line up along what imaginary plane in the center of the cell?
Metaphase plate
what phase number is this
4
what phase number is this
5
What do duplicated chromosomes appear as
Sister Chromatids
what enters the nuclear area
microtubules
Kinetochores
What separates in this phase
Sister Chromatids
how many daughter nuclei form
2
What is being grabbed in this phase
DNA
what do some microtubules attach to
kinetochores
Metaphase is preceded by this "transitional" stage where the nuclear envelope fully breaks down and spindle fibers first reach the chromosomes?
Prometaphase
Where do sister chromatids move to
Opposite sides of the cell
what reappears
nucleoli
What condenses in this phase
Chromatin
what do spindles attach to
chromosomes
If a human cell is in metaphase, this is the total number of sister chromatids present before they are pulled apart.
92
Does the cell elongate or shrink in this phase
Elongate
what happens to chromosomes
become less condesed
What begins to form in this phase
Miotic spindle
what is the full name for microtubules
astral microtubules
This critical regulatory mechanism ensures all chromosomes are properly attached to spindle fibers before the cell is allowed to proceed to anaphase.
M Checkpoint
Do the microtubules shrink or grow in this phase
Shrink
what is the name of the space in between cells in animal cells during this phase
cleavage furrow
