Mitosis vs Meiosis Quiz

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.

In mitosis, the two resulting cells are

• different from the starting cell and identical to each other.
• different from the starting cell and different from each other.

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.
