Chapter 12 Assignment
1. What part of the phage entered the bacterial cell following infection?
a. DNA
2. If 35S (radioactively labeled protein) was found in progeny phages rather than 32P
(radioactively labeled DNA), Hershey and Chase would have concluded that
a. phage protein enters the host cell.
3. In the Hershey and Chase experiment, radioactively-labeled
a. 32P labeled DNA remained inside the cells after vigorous shaking.
4. The correct structure of DNA components can be presented as
a. Phosphate–sugar–base.
5. Which of the following DNA molecules is the most stable?
a. GCGTGCAC
CGCACGTG
6. Nucleotide pairing between DNA strands allows the sequence of one strand to
determine the sequence of the complementary strand during DNA replication.
a. True
7. Choose the order below that most closely represents the order in which the following
proteins participate in DNA replication.
a. helicase → single-stranded binding protein → primase → DNA polymerase
8. What is the function of the enzyme primase during DNA replication?
a. To assemble a RNA primer at the origin of replication site
9. The short DNA segments formed on the discontinuously replicated strand are called
a. Okazaki fragments.
