Viral Replication and Pathogenesis Quiz

Reversal is not a step in the viral replication cycle.

HIV belongs to the Retroviridae viral family.

Viral envelope proteins primarily facilitate attachment to host cells.

Assembly involves the assembly of viral components into new virions during the viral replication cycle.

Enveloped viruses contain an envelope composed of host cell membrane and viral proteins.

Messenger RNA serves directly as a template for protein synthesis.

RNA polymerase synthesizes RNA from a DNA template during viral replication.

Positive-sense single-stranded RNA genomes are directly infectious upon entering the host cell.

Integrase is the viral enzyme responsible for integrating viral DNA into the host cell genome.

Reverse transcription is not a type of viral entry mechanism.

Viruses often hijack ribosomes to translate viral proteins.

Negative-sense single-stranded RNA genomes require a viral RNA polymerase for transcription.

Blockage of viral entry is not a mechanism of viral pathogenesis.

Ambisense viruses have both RNA and DNA in their life cycle.

Viral proteins often disrupt apoptosis to evade host immune response.

Antigenic variation is a common mechanism by which viruses evade host immune response.

Enhancement of cellular respiration is not a mechanism by which viruses cause disease.
