Biology: Cell Cycle Quiz Flashcards
When a cell is not dividing it is said to be in _____.
Interphase
The genetic material found inside the nucleus during interphase is called _____.
Chromatin
The genetic material changes during prophase into structures known as chromosomes which are attached by a point called the _____.
Centromere
After mitosis the daughter cells will be _____ to the parent cell.
Identical
Cells divide for three reasons: maintenance, repair and _____.
Tissue Growth
Cancer cells are cells that _____.
Divide Rapidly
DNA _____ occurs during the S phase.
Synthesis
Centrioles connect to chromosomes using _____.
Spindle Fibres
The cells that result from mitosis are called _____.
Daughter Cells
The phase the nucleus dissolves in is _____.
Prophase
Determine if the following statement is true or false, and if false correct the bolded word: During prophase the spindle fibres attach to the centromere and align the chromosomes in the middle of the cell.
False, Metaphase
Determine if the following statement is true or false, and if false correct the bolded word: The division or seperation of the cytoplasm and its contents is known as mitosis.
False, Cytokenesis
Determine if the following statement is true or false, and if false correct the bolded word: Cells spend most of their life cycle in interphase.
True
Determine if the following statement is true or false, and if false correct the bolded word: The stage of mitosis during which two nuclei are formed and the chromosomes uncoil is called telophase.
True
Determine if the following statement is true or false, and if false correct the bolded word: Anaphase is the stage in which the chromosomes duplicate.
False, Interphase
Determine if the following statement is true or false, and if false correct the bolded word: If a normal human cell has 46 chromosomes, each daughter cell will have 23 chromosomes.
False, 46
Determine if the following statement is true or false, and if false correct the bolded word: A mutation is a mass of abnormal cells that develops when cancerous cells divide and grow uncontrollably.
False, Tumour
Explain the reason why each cell must duplicate the genetic material before mitosis can occur.
Each cell must duplicate the genetic material before mitosis so it ensures the two daughter cells are identical to the parent cell. If your DNA isn’t replicated correctly, you basically become a different person after a while.
Explain the difference in cell division in a plant and an animal cell.
The difference between plant and animal cell division is that during cytokenesis, animal cells cleave into two new cells while plant cells form a new cell wall between the two nuclei. As well, only animal cells have centromeres.

A
What letter represents the stage in which the chromosomes are lined up in the middle of the cell?

Y
What letter represents the stage in which DNA replication occurs?
B
What letter represents the stage in which two identical daughter celles begin to form?
