Viral Structure, Replication, and Transmission Quiz

Viruses consist of a protein coat encapsulating genetic material.

Cellular penetration refers to the process of virus injecting its genetic material into host cells.

HIV, or Human Immunodeficiency Virus, causes AIDS.

Antibiotic treatment is not effective against viral infections.

Respiratory viruses typically do not enter through the gastrointestinal tract.

Viral capsid encloses and protects viral genetic material.

Ebola virus is an example of a zoonotic virus.

Circular RNA is not a type of viral genome.

Viral polymerase enzyme synthesizes viral RNA or DNA.

Spontaneous generation is not a method of viral transmission; it's a disproven theory.

Reverse transcriptase enzyme converts RNA into DNA in retroviruses.

DNA viruses have double-stranded genetic material.

Antiviral drugs target viral polymerases or proteases to inhibit replication.

RNA viruses frequently have segmented genomes.

Retroviruses integrate their genome into the host cell's DNA.

Exocytosis is not a method of viral entry into host cells.

Host range for a virus is primarily determined by host cell surface receptors.

Viral envelope assists in viral attachment and entry into host cells.

Direct contact with infected bodily fluids is not a mode of viral transmission from arthropod vectors to humans.

Enveloped viruses possess an outer lipid membrane obtained from the host cell.

Neuraminidase aids in releasing virions from infected cells during influenza infection.

Viroid is an infectious RNA particle lacking a protein coat.

Viruses evade host immune response by mutating surface antigens.

Antigenic shift involves the exchange of genetic material between different virus strains.

Viruses can cause cancer by inserting viral oncogenes into the host cell genome.
