DNA Function Quiz

Question 1: The order of amino acids in proteins depends on the order of bases in the DNA.
A. False
B. True

Question 2: Which part of the nucleotide stores the genetic information?
A. Nitrogen base
B. Deoxyribose
C. Ribose
D. Phosphate group

Question 3: During DNA replication, it is possible for the T residue in the template strand to form two hydrogen bonds with a T base on the new strand. This doesn't normally occur because:
A. The T-T basepair contains two of the smaller sized bases.
B. The two T-T hydrogen bonds will be weaker than the two hydrogen bonds between an A-T pair.
C. The normal A-T base pairing uses 3 hydrogen bonds, so it will be preferred.
D. DNA polymerase cannot incorporate T into the newly synthesized strands.

Question 4: PCR differs from DNA replication in which of the following ways?
A. Double stranded DNA is the product.
B. A polymerase is needed.
C. Primers are needed.
D. A single copy of DNA is made.

A. DNA Mutation
B. Base Titration
C. Gene Expression
D. DNA Replication

A. Animals
B. Plants
C. Bacteria
D. Viruses

Question 7: A typical PCR cycle consists of steps at different temperatures, typically 55, 78 and 98 oC. The correct order of these steps is?
A. 98, 78, 55
B. 55, 98, 78
C. 98, 55, 78
D. 78, 98, 55
E. 55, 78, 98
F. 78, 55, 98

Question 8: Which of the following statements is FALSE?
A. Both DNA replication and PCR use helicase.
B. Both DNA replication and PCR use a DNA template.
C. Both DNA replication and PCR use primers.
D. Both DNA replication and PCR use DNA polymerase.

Question 9: Skin cells perform very different functions compared to brain cells. On the molecular level, what makes skin cells different from brain cells in the same organism?
A. pH
B. Proteins
C. DNA
D. ATP

Question 10: Does the DNA in the skin cell have the same sequence of bases as the DNA in the brain cell of the same organism?
A. Yes, the sequence of bases should be the same in all cells of an organism.
B. No, some cells will have mom's DNA, other cells will have dad's DNA.
C. No, the DNA sequence will vary based on cell type.
D. Yes, the sequence of ALL DNA is the same.
