1. What is the first step in the initiation of
translation in bacteria?
a. The small subunit of the ribosome binds to the ribosome
binding site on the mRNA molecule.
b. The ribosome binds to the initiation codon on the mRNA
molecule.
c. The large subunit of the ribosome binds to the ribosome
binding site on the mRNA molecule.
2. How is protein synthesis
terminated?
a. A release factor recognizes the termination codon and enters
the A site.
b. a tRNA for the termination codon enters the P site.
c. a tRNA for the termination codon enters the A site.
3. Which of the following is NOT a reason why
proteins require assistance in folding during translation or
following denaturation?
a. During translation, the partially translated protein is a
random coil, unable to fold into any specific
conformation.
b. After denaturation, proteins may form insoluble aggregates
caused by an inability to shield their hydrophobic groups from
water.
c. During translation, partially translated proteins might begin
to fold incorrectly before the entire protein is
synthesized.
