      DNA Review Answers:

     1. C - Bacteriophages are viruses that specifically infect bacteria.

     2. C - Guanine bonds with Cytosine during DNA replication.

     3. C - RNA Polymerase is not involved in DNA replication; rather, it is important for transcription of DNA into RNA.

     4. A - Both Griffith and Avery used bacterial transformation to show that DNA is the genetic material.

     5. C - Inversion is when the DNA nucleotides are inserted in backwards fashion. It is not when a portion of a chromosome attaches to another chromosome.

     6. C - Phosphodiester bonds join nucleotides together during the process of DNA replication.

     7. E - The leading strand's template is oriented in the 3' to 5' direction, allowing DNA Polymerase to move continuously from 5' to 3'.

     8. D - Okazaki fragments are joined together by the action of DNA Ligase.

     9. F - DNA Helicase is responsible for unzipping the double-stranded DNA molecule to form the replication fork.

     10. E - The leading strand is formed continuously in the 5' to 3' direction by the action of DNA Polymerase.
