1. Where are DNA molecules found in an animal’s body?
A. Inside all types of cells in an animal’s body
B. Inside an animal’s body but not inside any cells in an animal’s body
C. Inside sex cells but not any other types of cells in an animal’s body
D. Inside blood cells but not inside any other types of cells in an animal’s body
2. How does genetic information in a fertilized egg cell (an egg cell that has combined with a
sperm cell) compare with the genetic information in the skin cells of the adult organism that
develops from the fertilized egg cell?
A. The skin cells in the adult organism contain the same genetic information that was in
the fertilized egg cell
B. The skin cells in the adult organism still contain some of the genetic information that
was in the fertilized egg cell but not very much of the information
C. Some of the skin cells in the adult organism contain all of the genetic information that
was in the fertilized egg cell, but other skin cells contain just a little of the information
D. None of the skin cells in the adult organism contains any of the genetics information
that was in the fertilized egg cell
3. Which of the following does provide information for DNA?
A. Both the types of amino acids that make up a protein, and the sequence of those amino
acids
B. The types of amino acids that make up a protein molecule, but not the sequence of
amino acids
C. The sequence of amino acids that make up a protein molecule, but not the types of
amino acids
D. Neither the types of amino acids that make up a protein, nor the sequence of those
amino acids
4. Many different types of protein molecules are made within cells. Which of the following could
be influenced by the actions of those protein molecules?
A. Both an organism’s physical characteristics and its behaviors
B. An organism’s physical characteristics but not its behaviors
C. An organism’s behaviors but not its physical characteristics
D. Neither an organism’s physical characteristics nor its behavior
5. A skin cell from a cow contains 60 DNA molecules. How many DNA molecules are found in
new skin cell that develop as the cow grows?
A. 30
B. 60
C. 90
D. 120

6. A mouse’s tail gets caught in a mousetrap. When the mouse pulls free, its tail gets cut off. If
the mouse has babies later, how will this affect the length of the tails of its babies?
A. It will affect the length of the tails of all the babies
B. It will affect the length of the tails of some of the babies
C. It will not affect the length of the tails of any of the babies
D. It depends on how old the mouse was when its tail was cut off
7.
8. Humans, dogs, and trees are all living things. In which of these organisms would you find DNA
molecules?
A. Only in humans
B. Only in humans and dogs
C. In humans, dogs, and trees
D. DNA molecules are not found in any of these organisms
9. Fully-grown adults are much larger in size than young children. What happens to the cells of
the body during the growth of a child?
A. The cells of a growing child divide to make more cells, and those cells are each half the
size as the cells were before they divided. The cells do not grow before they divide
again.
B. The cells of a growing child divide to make more cells, and those cells grow to become
the same size as the cells were just before they divided.
C. The cells of the body of a growing child grow, but the number of cells stays the same.
D. The size and number of cells in the body of a growing child stay the same.

10. A student wants to build a physical model of DNA as a part of his science course assignment.
Which of the following things is absolutely essential for him to build a DNA model?
A. He must accurately represent the relative distances between nitrogenous base pairs,
the phosphate groups, and 5- carbon sugar deoxyribose.
B. He must use different colored candy, liquorice cords etc. to represent the different parts
of DNA.
C. He must make sure that the parts of the model (nitrogenous base pairs, the phosphate
groups, etc) should exactly look like the parts of “real” DNA because all aspects of the
thing being modeled need to be modeled accurately.
D. He must ignore some parts of the DNA structure since it is hard to build those parts.
