In many ways, the regulation of the genes of a particular group of viruses will be similar to the regulation of the host genes. Therefore, which of the following would you expect of the genes of the bacteriophage?
A) regulation via acetylation of histones
B) positive control mechanisms rather than negative
C) control of more than one gene in an operon
D) reliance on transcription activators
E) utilization of eukaryotic polymerases

Question

Control of more than one gene in an operon is common in bacteriophages, as well as in bacteria. This allows for coordinated expression of multiple genes that contribute to a specific function, such as viral replication. While some bacteriophages may utilize transcription activators or rely on positive control mechanisms, these are not universally characteristic of all phages. Acetylation of histones and utilization of eukaryotic polymerases are features unique to eukaryotes, and would not be expected in bacteriophages.
