Amoeba Sisters: Mitosis vs. Meiosis Challenge!

Interphase is when a cell is growing, replicating its DNA, and carrying out cell processes. Which of these is correct regarding when Interphase happens?

• It occurs once before mitosis and once before meiosis.

• It occurs once before mitosis and twice before meiosis.

• It occurs once before mitosis and does not occur before meiosis.

• It does not occur before mitosis and occurs once before meiosis.

Why would it be important to replicate DNAbefore a cell divides in mitosis or meiosis?

• In order for enough genetic information to be transferred into daughter cells.

• In order for the cell to be able to increase in size.

• In order for the DNA to be contained in the nucleus.

• In order for the cell to re-order the DNA sequencing in the new cells.

In meiosis, crossing over occurs in prophase 1. What is the significance of crossing over?

• Crossing over ensures chromosomes are evenly divided into daughter cells.

• Crossing over can lead to genetic variation in daughter cells.

• Crossing over can create mutations in daughter cells.

• Crossing over allows chromosomes to line up in the center of the cell.
