Eukaryotic cells undergo mitosis as part of the cell cycle. What does a cell produce as a result of mitosis?
Two cells with the same genetic information
Two cells that are larger than the original cell
Two cells with genetic material that is different from the original cell
Two cells that no longer participate in the stages of the cell cycle
The cell cycle is a series of events that takes place in a cell as it
replicates DNA.
produces specialized cells.
grows and divides.
divides after checkpoints.
A cell spends most of its time in what is called ________, and during this time it grows, replicates its ___________, and prepares for cell division. The cell then leaves interphase, undergoes ______, and completes its division. The resulting cells, known as daughter cells, each enter their own interphase and begin a new round of the cell cycle.
interphase, chromosomes, division.
interphase, chromosomes, mitosis.
cell cycle, chromosomes, division.
cell cycle, chromosomes, mitosis.
During the G1 phase, the cell
divides
separates chromosomes
replicates DNA
grows

What three things does a cell have to do to go through the cell cycle? (check all three)
