Prophase
This happens to chromatin in prophase
What is condenses?
Microtubules connect to this cell component.
What are kinetochores.
This is the first thing that happens to sister chromatids in anaphase.
What is-- they separate?
This happens to chromosomes during this phase.
In this phase the nuclear envelope fragments.
What is Prometaphase?
This feature of the cell disappears during prophase
What is the nucleoli?
In prophase, the nuclear area begins to have these in it.
What is microtubules
Name one key event that occurs during anaphase.
Possible options: the microtubules shorten, the sister chromatids are drawn apart, the cell elongates, the sister chromatids move to opposite ends of the cell
The difference between telophase and cytokinesis
What is that telophase regards the splitting of chromosomes into two distinct nuclei, while cytokinesis regards the splitting of cytoplasm.
In this phase chromosomes are lined up along the center of the cell.
What is metaphase.
Duplicated chromosomes appear as _____.
What is sister chromatids?
What is the metaphase plate?
Cells in anaphase can be identified sometimes by this change in shape.
What is-- they are elongated?
Two _________ _______ form in this phase.
The phase in which chromatin condenses.
What is prophase?
Centrosomes move in this direction during prophase.
In metaphase the centrosomes are in this position.
What is at opposite poles?
This causes the sister chromatids to move to opposite sides of the cell.
What is the shortening of the microtubules?
These cell components reappear during telophase.
What are nucleoli?
The phase in which there are two nuclei.
What is telophase.
This mitotic spindle begins to form during prophase. What is its purpose?
The mitotic spindle later forms spindle fibres, which connect to and pull apart the sister chromatids to separate chromosomes for each daughter cell.
Name two key events in prometaphase
What are 1) nuclear envelope fragments and 2) microtubules enter nuclear area and some attatch to kinetochores.
In this phase, the poles move in which direction.
Describe the difference between cytokinesis in plant and animal cells.
What is --
in animals a cleavage furrow appears due to a contractile ring of actin filaments.
in plants vesicles produces by the Golgi travel to the middle of the cell and form a cell plate.
Name the 5 stages of mitosis in order.
Prophase, Prometaphase, Metaphase, Anaphase, Telophase and Cytokinesis.
