What distinguishes replication of all viruses from replication of any other obligate intracellular
parasites?

Replication of viral genomes takes place in the cytoplasm, not the nucleus.
Virus replication is by binary fission.
Virus replication takes place only in living “host cells”.
Viral genomes are copied by polymerases encoded by the genomes of other organisms.
Production of new virions requires disassembly of the “parental” virion.*

In Influenza virus replication, which of the following is NOT carried out by a host-cell protein or
organelle?


Production of energy in the form of ATP.
Translation of viral proteins.
Synthesis of nucleotides for incorporation into viral genomes and transcripts.
Transcription of viral messenger RNA’s.
Synthesis of lipids that will become incorporated into viral envelopes. *
