1. The image below shows a microscopic image of plant cells going through different stages of mitosis.
Which stage identification is correctly justified?
A.
B.
C.
D.
The separation of sister chromatids indicates that D is telophase.
The missing nuclear envelope indicates that C is metaphase.
The condensed chromatin indicate that A is prophase.
The presence of a nucleus indicates that B is prophase.

2. Some organisms, such as bacteria, reproduce asexually; whereas, other organisms reproduce
sexually. Which statement correctly states why one type of reproduction is beneficial over the
other?
A. Asexually reproduced offspring are more genetically diverse.
B. Sexual reproduction produces organisms that are genetically diverse.
C. Sexual reproduction can produce a large number of offspring very quickly.
D. Asexual reproduction produces offspring genetically different from parents.

3.
Meiosis and mitosis have different stages that share some similarities and differences. What
distinguishes Prophase during mitosis from Prophase I during meiosis?
A.
B.
C.
D.
During meiosis Prophase I, chromatin condenses and shortens.
During Prophase, chromatin moves to the central plane of the cell.
During mitosis Prophase, spindle fibers pull the sister chromatids apart.
During meiosis Prophase I, crossing over occurs which increases genetic diversity.

4.
A scientist wants to increase the chance of pregnancy in mice. He gives the mice a hormone that
causes them to produce more gametes. Which of the following statements justifies which process
the cells went through after the hormone injections?
A. Mitosis, because daughter cells genetically identical to the parent cell are needed for
reproduction.
B. Meiosis, because the cells produced need to be diploid rather than haploid.
C. Meiosis since it produces haploid cells needed for reproduction.
D. Mitosis because more cells will be produced at a faster rate.

5.
Cancer is the uncontrolled growth of cells. Which of the following would be most likely to cause
cancer?
A. Mutations in regulatory proteins during the cell cycle may cause affected cells to divide
uncontrollably.
B. During the synthesis stage, crossing over will cause cells to divide without inhibition
C. Cells, which come in contact with cancerous cells, become cancerous themselves.
D. A bacterial infection modifies a cell, causing it to grow out of control.
6.
SC.912.L.16.14
During interphase of the cell cycle, a muscle cell was determined to contain less mitochondria than needed.
What would most likely happen to this cell?
A. The defective cell will proceed through GAP1 and GAP2, but be destroyed during mitosis.
B. The unacceptable cell would most likely be detected during GAP1 and removed from the cell
cycle.
C. The problem cell would be detected during the S-phase of the cell cycle and the cell will be
destroyed.
D. The problem will be corrected during the synthesis phase, then the cell will continue to divide
through mitosis.

7. A cell going through meiosis changes as it divides. Which process is most important for producing
haploid cells?
A. independent assortment
B. reduction division
C. crossing over
D. synthesis

8. Scientists have developed genetically modified crops that are more resistant to damage by frost,
chemicals, and drought. Which statement correctly justifies a drawback of bioengineered crops?
A.
B.
C.
D.
Bioengineered crops are more fragile because of the changes in their genes.
Food production is decreased since the genetic modifications are not beneficial.
Disease resistance is a negative side effect of the genetic modification of plants.
Plants lose diversity as a result of the production of plants with the same modifications.
SC.912.L.16.10
9. Which of the following uses of genetically modified organisms would cause the greatest concern to the
public?
A. Using gene therapy to replace defective genes in patients with sickle cell anemia.
B. Incorporating recombinant DNA into plasmids so that bacteria produce insulin for patients
with diabetes.
C. A gene is transferred into to the DNA of a plant, enabling it to produce a toxin that kills crop
eating caterpillars by poisoning their gut.
D. Recombinant DNA being used to enable a bird flu to transfer from human to human in order
to study the genetics of human to human transfer.

10. In 1973, Stanley Cohen and Herbert Boyer inserted a toxic gene from an African clawed frog into the
plasmid of a bacterium. The bacterium then began to produce the toxin. How did this discovery most
impact society?
A. It led to other life-saving chemicals being produced by recombinant DNA.
B. It revealed that bacterial DNA can be used to make an entirely new DNA strand.
C. It allowed other toxic chemicals to be produced from genetically engineered frog
DNA.
D. It demonstrated how a DNA toxin from one organism can be used to kill another
organism.
