Interphase
how many steps are there in interphase
3
What happens in Prophase?
chromatin shortens and condenses to form chromosomes
What happens in Metaphase?
Spindle fibers help more chromosomes to the center of the cell
What is anaphase?
The stage of meiotic or mitotic cell division is in which the chromosomes move away from one another to opposite poles of the spindle.
What is Telophase?
The final phase of cell division, between anaphase and interphase, is in which the chromatids or chromosomes move to opposite ends of the cell and 2 nuclei are formed.
What does the G1 phase do?
It makes the immature cells grow into adult size cells
What happens to the nuclear membrane?
It breaks down
What does the fully formed spindle consist of, by the time of metaphase?
Poles, Asters, Fibers
What divides at the beginning of anaphase?
The centromeres uniting the sister chromatid
What is Cytokinesis?
The cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into 2 daughter cells.
What is the process of Interphase?
Interphase is where cells go after there done dividing
What structure pulls the spindle fibers to attach chromosomes to the opposite ends of the cell?
Centrioles
What is a plane perpendicular to the axis of the spindle and equidistant from the poles?
Metaphase Pole
What do sister chromatids become after they separate?
Daughter chromosomes
How many daughter cells are formed after cytokinesis?
2
In the S stage of interphase.....
The DNA is replicated
Where do centrosomes move at the beginning of prophase?
Away from each other, toward opposite ends of the nucleus.
What is attached to centromeric spindle fibers, and lines up at the metaphase plate?
Chromosomes
What do daughter chromosomes have?
Centromeres and a single chromatid
What disappears during Telophase?
The spindle
What is the one thing Interphase has that the other stages don't?
A nucleus
What are centromeres attached to, after the chromosomes become attached to the spindle fibers?
Centromeric fibers
Where do polar spindle fibers reach?
Beyond the metaphase plate, they overlap
What accounts for the movement of the daughter chromosomes?
The centromeric spindle fibers shortening and polar spindle fibers push the poles apart as they lengthen and slide past each other
Does each daughter cell contain the same number or a different number of chromosomes as the original parental cell?
Same
