Mitosis Vs. Meiosis

When a cell is not actively dividing, it is in what phase?

• interphase
• anaphase
• prophase
• telophase

A cell with 10 chromosomes go through meiosis. What is the end result of the process

• 4 cells with 10 chromosomes each
• 2 cells with 10 chromosomes each
• 4 cells with 5 chromosomes each
• 2 cells with 5 chromosomes each

After meiosis is complete, the new cells:

• are all identical
• are all different
• are half identical and half different
• are all stretched out

Meiosis makes sperm and egg cells. In humans, sperm and egg cells each have _____ chromosomes. Therefore a fertilized human egg cell (sperm and egg cell combined) would create a cell with _____ chromosomes.

• 23, 46
• 46, 23

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.
