General Info
How many daughter cells are made at the end of mitosis?
Two
During early prophase, do chromosomes condense or expand?
Condense
True or False: Chromosomes create a circle around the outside of the cell during metaphase
False: Chromosomes line up single file in the middle of the cell during metaphase
During anaphase, sister chromatids do what?
Separate (pull apart) and move to opposite ends of the cell
How many new nuclei form during telophase?
Two
True or False: Daughter cells produced during mitosis are genetically identical
True
This structure, made from microtubules, forms to move chromosomes around
The Mitotic Spindle
True or False: Metaphase is the 3rd step in mitosis
False: It is the second step
PMAT
As chromosomes move toward the poles, what happens to the overall shape of the cell?
The cell elongates
In this phase, do chromosomes condense even more or do they decondense and expand?
Decondense and expand
What disease is defined by uncontrolled cell division and the inability of cells to stop undergoing mitosis?
Cancer
This structure, responsible for making the ribosomes, disappears during early prophase
Hint: It is located in the nucleus
The Nucleolus
True or False: Sister Chromatids have already separated by metaphase
False: Sister Chromatids separate during the the phase after metaphase called anaphase
What pulls sister chromatids apart during anaphase?
Spindles or Spindle Fibers
During Telophase, this structure, which was used to move chromosomes, finally breaks down.
The Mitotic Spindle
Mitosis occurs in these type of cells, rather than germ cells
Somatic Cells
In late prophase, this protective layer breaks down to release the chromosomes.
The Nuclear Envelope or The Nuclear Membrane
True or False: Metaphase is an important checkpoint to make sure that the cell's chromosomes are intact and have the proper number
True: Chromosomes lining up in the middle of the cell make it convenient for cell machinery to check chromosome health and number
These types of proteins drive the movement of chromosomes toward opposite ends.
Motor Proteins
These two structures, which disappeared in Prophase, reappear during Telophase.
The Nuclear envelope and the nucleolus
Chromosomes in the nucleus have 2 interconnected copies called...?
Sister Chromatids
These specific proteins on sister chromatids serve as the attachment point for microtubules.
Kinetochores
True or False: If a mother cell has 12 chromosomes, then it will produce 2 daughter cells with 12 chromosomes each during mitosis
True: Mitosis makes 2 genetically identical daughter cells
Motor proteins transport these two things during anaphase.
Chromosomes and microtubules
This process, which often overlaps with the final stages of mitosis, is the physical division of the cytoplasm to form two separate cells.
Cytokinesis
