WorksheetsCell Cycle and Mitosis Review
Total questions: 13
Worksheet time: 15mins
During the "s" phase of the cell cycle, DNA is duplicated. Why is this important?
Allows for each daughter cell to be genetically DIFFERENT.
Allows for each daughter cell to be genetically IDENTICAL
Allows for each daughter cell to have 2X the amount of DNA as the parent cell.
Allows for each daughter cell to have half the amount of DNA as the parent cell
What happens in prophase of mitosis?
The chromosomes become visible; nucleus disappear; spindles form
The chromosomes align in the middle of the cell
The sister chromatids separate
The chromosomes uncoil into chromatin; nucleus reappears; spindles disappear
What can occur to an organism if the cell cycle is not regulated properly?
The organism will require more food energy because of the cell growth will increase
The cell cycle will proceed faster and create more cells causing it to grow faster
Some cells will go through apoptosis but nothing will change for the organism
Cancer can be caused and non-functioning cells can be produced
What would be the outcome for an organism if its cells cannot grow and divide properly?
It will die because specialized & functioning cells are not being replaced
Nothing, it will continue to live and reproduce as normal
It will slow down because its cells will be old
It will get smaller because no new cells are being made to grow
Why is it necessary for the cell cycle to have regulation (checkpoints)?
To ensure the cell functions properly before division
To ensure that the old cell is still functional
To ensure that the new cell is functional after division
So that the DNA unfolds properly
