In the SsRNA Phage MS2, the Replicase Protein Binds to the Start

question 17

Multiple Choice

In the ssRNA phage MS2, the replicase protein binds to the start codon of the coat protein gene.Which of the following describes the reason for this binding?

• A) It prevents replication and translation from occurring simultaneously.
• B) It initiates synthesis of the minus-strand copy of the genome.
• C) It enhances binding of the ribosome to the coat protein gene.
• D) It disrupts the stem-loop structure that prevents replication of the viral genome.
• E) It exposes the 3' end of the genome which allows the replicase to begin RNA synthesis.
