When we're talking about mitosis, we need to remember that there's four big steps of mitosis, one step that's kind of like an ending punctuation to it, and then another step that just completes the cell cycle.
00:16
So for mitosis, i have prophase, metaphase, anaphase, and telophase.
00:22
Cytokinesis is the ending punctuation of mitosis that actually is the complete separation of the two cells.
00:30
Interphase is just the rest of the cell's life.
00:33
In the cell cycle.
00:35
So as we go through this worksheet, we're just going to match out which phase applies to each description.
00:41
So for number one, says the sister chromatids are moving apart.
00:45
That is anaphase.
00:53
Number two, the nucleolus begins to fade from view, prophase.
01:00
Number three, a new nuclear membrane is forming around the chromosomes.
01:06
Telophase.
01:10
Number four, the cytoplasm is being divided.
01:13
That's cytokinesis.
01:15
And cytok is in both words, cytoplasm and cytokinesis.
01:21
Number five, the chromosomes become visible.
01:24
That's prophase.
01:27
Number six, the chromosomes are located at the equator of the cell.
01:32
That's metaphase.
01:37
Number seven, the nuclear membrane begins to fade from view.
01:41
Profase again.
01:46
Number eight, the division or cleavage furrow appears, where it's looks like the cells are divided, but they're not totally separated yet.
01:54
That's anaphaease.
01:57
Also in anaphase, the chromosomes move towards the poles of the cell.
02:07
Number 10, chromatids line up along the equator.
02:10
That's metaphase.
02:12
Again, chromosomes meet in the middle at metaphase.
02:17
11, the spindle fibers form.
02:19
These will eventually pull those chromosomes apart.
02:22
This is prophase.
02:24
Back at the beginning of mitosis...
