Prophase
Sister Chromatids.
What do duplicated chromosomes appear as?
The phase that comes after prophase and is characterized by the breakdown of the nuclear envelope.
What is pro metaphase?
Metaphase is characterized by the alignment of chromosomes _______.
In the center of the cell.
Sister chromatids.
What is separating during anaphase?
Two identical daughter nuclei.
What forms during telophase?
Centrosomes move away from each other in prophase.
What moves away from each other during prophase?
Where the spindle fibers attach.
What is the kinetochore?
Opposite poles of the nucleus.
Where are the centrosomes in Metaphase?
That both daughter cells receive the same exact number of chromosomes.
What does anaphase ensure?
The nucleoli.
What reappears during telophase?
DNA & proteins that are condensed during this phase.
What is chromatin?
The structure capturing chromosomes.
What are Microtubules?
The chromosomes align in the center of the cell.
Where are the chromosomes in metaphase?
Where the chromatids are being pulled towards in anaphase.
What are centrosomes?
They appear in animal cells during the separation of the two cells due to the pinching of the cell membrane.
What are cleavage furrows?
_____ that disappears during prophase allowing for spindle formation and the chromosomes to condense.
What is the nucleoli?
The structure that breaks down allowing chromosomes to interact with spindle fibers
What is the nuclear envelope?
Where the microbuses are attached.
What is a kinetochore?
They shorten in order to pull the chromatids towards opposite poles.
What role do spindle fibers play in anaphase?
They appear in plant cells and are produced by the Golgi Complex in order to form a cell plate.
What are vesicles?
It begins to form in prophase and becomes essential for chromosome segregation.
What is the mitotic spindle?
The freeing of the sister chromatids from the nucleus.
What is necessary for separating the nuclear material into two cells?
In this phase, the chromosomes are aligned in the center in order to produce two identical cells
What are daughter cells?
The protein that breaks down, dissolving the link between the two chromatids during prophase.
What is cohesin?
They loosen and turn back into chromatin.
How do chromosomes act during telophase?
