Later lessons in this course will require you to have a solid understanding of mitosis. Use the drag and drop activity below to make sure you know the most important events that occur at each phase. Draw a line between the phase name and the phrase that describes it.
|
Prophase
|
Clear chromosomes
Mitotic spindle forms
Division
|
During this first phase, the cell forms devices that it will use to separate the chromatids.
During this first phase, the cell forms devices that it will use to separate the chromatids.
|
Metaphase
|
Chromatids line up in the middle
Pairs of chromatid separate
Two nuclei form
|
During this phase, the chromatids are in the middle of the cell, ready to be separated.
During this phase, the chromatids are in the middle of the cell, ready to be separated.
|
Anaphase
|
Spindles form at either end
Chromatids break down
Pairs of chromatids separate
|
At this point, the sets of chromatids separate into sets of chromosomes.
At this point, the sets of chromatids separate into sets of chromosomes.
|
Telophase
|
A new nuclear envelope forms
The cell divides
Chromatids separate
|
This is the phase when each "new" set of chromosomes is surrounded by a nuclear envelope.
This is the phase when each "new" set of chromosomes is surrounded by a nuclear envelope.
|
Cytokinesis
|
The cell cleaves and divides
Spindle fibers form
Sister chromatids separate
|
In this final phase, a furrow forms in the cell wall, and the cell finally separates into two new daughter cells.
