DNA Replication, Mitosis, and 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.
• identical to the starting cell and different from each other.
• identical to the starting cell and identical to 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.

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
• 2, 4
• 50, 100
