Question

There are viruses, called bacteriophage, that infect bacterial cells. Following viral entry, the cell begins to synthesize viral DNA and viral proteins, leading to the production of mature virus and the death of the bacterial cell. During the course of viral infection, transcription of bacterial genes is turned off so that transcription of viral genes predominates. Which of the following is the most likely explanation for how the virus manages to shift transcription from bacterial genes to its own genes?

it synthesizes a viral RNA polymerase that recognizes only viral promoters

it synthesizes a viral DNA polymerase that recognizes only viral origins

it synthesizes a viral sigma subunit that directs the bacterial RNA polymerase to viral promoters

it has special viral ribosomes that only translate viral proteins

a.)

it synthesizes a viral RNA polymerase that recognizes only viral promoters

b.)

it synthesizes a viral DNA polymerase that recognizes only viral origins

c.)

it synthesizes a viral sigma subunit that directs the bacterial RNA polymerase to viral promoters

d.)

it has special viral ribosomes that only translate viral proteins
