7th grade quiz 1

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

• 50%

Which is that phase?

• Prophase

• Metaphase
