SBI3U Mitosis Quiz Flashcards
In which phase of mitosis/the cell cycle does the nucleolus appear within each new nucleus?
Telophase.
In which phase of mitosis/the cell cycle do the centromeres divide?
Anaphase
In which phase of mitosis/the cell cycle do the chromosomes become visible?
Prophase
In which phase of mitosis/the cell cycle do the spindle fibres begin to form?
Prophase
In which stage of mitosis/the cell cycle does DNA replicate?
Interphase
In which stage of mitosis/the cell cycle do replicated strands move toward opposite poles?
Anaphase
In which stage of mitosis/the cell cycle do the chromosomes form a line across the middle of the cell (the equatorial plate)?
Metaphase
In which stage of mitosis/the cell cycle does the nuclear membrane form around each set of chromosomes?
Telophase
In which stage of mitosis/the cell cycle does the cell grow?
Interphase
In which stages of mitosis (including interphase) is the nucleus present?
Interphase, prophase, and telophase.
In which stages of mitosis (including interphase) is the nucleolus present?
Interphase, prophase, and telophase.
In which stages of mitosis (including interphase) is the nuclear membrane present?
Interphase, telophase, and somewhat visible in prophase (but beginning to disassemble)
In which stages of mitosis (including interphase) are the chromatin visible?
Interphase and telophase.
In which stages of mitosis (including interphase) are the chromosomes present?
Prophase, metaphase and anaphase.
In which stages of mitosis (including interphase) are the spindle fibres present?
Prophase, metaphase and anaphase.
What is one main difference in cell division in a plant cell vs. an animal cell?
In cytokinesis, a new cell wall forms in a plant cell between the two new nuclei of the daughter cells, whereas the existing cell membrane of an animal cell pinches off (creating a furrow).
What is the end result of mitosis (including cytokinesis)?
Then end result is complete and equal division of the nucleus, with two new daughter cells containing identical genetic information to the parent cell.
Describe how the cell prepares for mitosis.
It doubles its chromosomes and grows.
What happens to the cell during interphase?
The cell grows, making protiens, producing wastes and doubling chromosomes.
During mitosis, in which stage do the centromeres divide?
Anaphase.
In which mitosis stage do the centrioles move to opposite ends of the cell?
Prophase
In which step of mitosis does the nuclear membrane form around each mass of chromosomes?
Telophase.
In which step of mitosis do the chromosome strands separate toward opposite ends of the cell?
Anaphase
In which step of mitosis are copies of each chromosome made?
Interphase
In which step of mitosis does the cell membrane pinch together and the cytoplasm of the cell divide?
Cytokinesis
In which step of mitosis does the nuclear membrane disappear?
Prophase
In which step of mitosis do the daughter cells form?
Cytokinesis
In which step of mitosis do the chromosomes line up along the equatorial plate?
Metaphase
Which step of the cell cylce takes up most of the cell’s life?
Interphase
When in the cell cycle does DNA replicate?
During interphase.
When during the cell cycle do the centrioles divide?
Interphase
When in the cell cycle do the chromatin condense into chromosomes?
Prophase
When in the cell cycle does the nucleolus fade?
Prophase
When in the cell cycle do the microtubules of the cytoskeleton (responsible for the cell’s shape, movement/motility and attachment to other cells) disassemble?
Prophase
When in the cell cycle are microtubules used to grow the mitotic spindle from the region of the centriole?
Prophase
When in the cell cycle are the chromosomes pulled to the cell poles by the spindle fibres?
Anaphase
When in the cell cycle do the daughter chromosomes arrive at the poles of the cell?
Telophase
When in the cell cycle do the spindle fibres disappear?
Telophase
When in the cell cycle do the microtubules reorganize themselves into a new cytoskeleton?
Cytokinesis
