What happens during the lytic cycle of viruses? A large number of phages are released at a time. Viral DNA is incorporated into the host genome. Many bacterial cells containing viral DNA are produced. The virus-host relationship usually lasts for generations. The viral genome replicates without destroying the host.

Which one of the following is not true for virus, obligate intracellular parasites?     Viruses cannot generate energy outside of cells     Viruses cannot synthesize proteins outside of cells     Enveloped viruses require host cell membrane to obtain their envelopes     Viruses must degrade host cell DNA in order to obtain nucleotides

A patient is admitted to the hospital with a viral infection and is immediately treated with broad-spectrum antibiotics. How will the course of the infection be affected by this treatment? The infection's length will remain the same because viruses do not have DNA or RNA, and so antibiotics do not affect them. The infection's length will be shorter because antibiotics can prevent viral entry into the cell by binding to host-receptor proteins. The infection's length will remain the same because antibiotics have no effect on eukaryotic cells or viruses. The infection's length will be shorter because antibiotics activate the immune system, and this decreases the severity of the infection.
