1.
Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?
a)
In order for genetic information to be transferred into daughter cells.
b)
In order for the cell to be able to increase in size.
c)
In order for the DNA to be contained in the nucleus.
d)
In order for the cell to re-order the DNA sequencing in the new cells.
2.
In mitosis, the two resulting cells are
a)
different from the starting cell and identical to each other.
b)
different from the starting cell and different from each other.
c)
identical to the starting cell and different from each other.
d)
identical to the starting cell and identical to each other.
3.
In meiosis, crossing over occurs in prophase 1. What is the significance of this event?
a)
This process ensures that chromosomes are evenly divided into daughter cells.
b)
This process can lead to genetic variation in daughter cells.
c)
This process can create gaps in the chromosome DNA for RNA to bind.
d)
This process allows for spindles to connect to the chromosomes in order to pull chromosomes apart.
4.
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.
a)
23, 46
b)
46, 23
c)
2, 4
d)
50, 100
5.
In meiosis, the four resulting cells are
a)
identical to the starting cell and different from each other.
b)
different from the starting cell and different from each other.
c)
identical to the starting cell and identical to each other.
d)
different from the starting cell and identical to each other.
