Virology and Viral Life Cycles Quiz

dsDNA is a type of viral genome, making this answer incorrect.

Spikes on the viral surface facilitate attachment to host cell receptors.

RNA viruses often exhibit a high mutation rate due to the lack of proofreading mechanisms.

Transcription is a cellular process, not a method of viral entry.

Mammals employ various immune mechanisms including innate and adaptive responses against viruses.

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

Penetration refers to viral entry, not exit from host cells.

Fomite transmission involves indirect transmission through inanimate objects.

Viral polymerase synthesizes new copies of the viral genome during replication.

Antiviral drugs typically target viral nucleic acids to inhibit viral replication.

Reverse transcriptase catalyzes the synthesis of DNA from RNA.

During assembly, viral components come together to form mature virions.

The capsid provides protection to the viral genome.

Lytic replication cycle involves host cell lysis for viral progeny release.

The viral envelope aids in attachment to host cells.

Translation involves the synthesis of proteins, not transcription which is the synthesis of RNA.

Helicase unwinds the DNA duplex during replication.

During release, mature virions are released from the host cell.

DNA viruses can integrate their genome into the host cell genome, unlike RNA viruses.

Penetration involves the injection of viral genetic material into the host cell.

Ebola virus is notorious for causing hemorrhagic fever in humans.

Endonuclease cleaves host mRNA to generate fragments during viral mRNA synthesis.

SARS-CoV is the virus responsible for SARS.

Varicella-zoster virus causes chickenpox.

Measles virus is the causative agent of measles.
