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 its occurence?

• 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 DNA before a cell divides in mitosis or meiosis?

• In order for 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.

• body cells
• sperm cells
• egg cells

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

• This process ensures that chromosomes are evenly divided into daughter cells.
• This process can lead to genetic variation in daughter cells.
• This process can create gaps in the chromosome DNA for RNA to bind.
• This process allows for spindles to connect to the chromosomes in order to pull chromosomes apart.

Mitosis is useful for the creation of new cells which is important for all of the following EXCEPT

• organism growth.
• repair of damage.
• replacement of worn out cells.
• generation of gametes.

• 23, 46
• 46, 23
• 2, 4
• 50, 100
