A. Hydrophobic regions
B. Hydrogen bonding
C. Conduction of heat
D. Disulfide bonds
E. Ionic bonding

A. Non-polar amino acids
B. Polar and uncharged amino acids
C. Polar and charged amino acids
D. Peptide bonds
E. L-form isomers
3. Which of the following statements is the MOST ACCURATE in regards to the DNA molecular structure?
A. DNA is a single stranded molecule with secondary and tertiary structures of a common protein.
B. DNA strands run in the same direction and are parallel to each other in a linear fashion to keep the DNA molecule intact.
C. The DNA molecule has a double stranded spiral shape with two types of grooves for protein interactions.
D. The phosphodiester bond formed between the carbon atoms of two adjacent ribose sugars facilitates the overall shape of the DNA molecule.
E. The overall shape of the DNA molecule is determined by base pairing between two purines (adenine and guanine) or two pyrimidines (cytosine and thymine).

C. Initiation
D. Translocation
E. Termination

7. Which of the following statements is the LEAST ACCURATE about DNA polymerase delta?
A. This enzyme starts adding polynucleotides to the newly synthesized DNA chain after an RNA-DNA primer is formed on both the leading and lagging strands.
B. This enzyme can synthesize about 200 nucleotides of DNA in the lagging strand before it reaches the RNA primer of the next Okazaki fragment.

D. This enzyme is also considered a 3' to 5' exonuclease that proofreads the newly synthesize DNA to detect and repair DNA changes.
E. This enzyme has the capabilities of an RNA polymerase and completes DNA synthesis at the end of the chromosomes.

8. Which of the following DNA mutations will MOST LIKELY produce a defective mRNA with a different reading frame than normal?
A. Point Mutations
B. Frameshift
C. Missense
D. Nonsense
E. Silent
