#1
Which of the following is NOT a characteristic of viruses?
They can reproduce on their own.
ExplanationViruses lack the cellular machinery for independent reproduction.
#2
What is the primary function of a viral capsid?
To protect the genetic material of the virus.
ExplanationThe capsid acts as a protective shell around the viral genome.
#3
Which of the following is NOT a type of viral genome?
Reverse-transcribing RNA (RT-RNA)
ExplanationRT-RNA is not a recognized type of viral genome.
#4
What is the function of the viral envelope?
To aid in the release of viral particles from host cells.
ExplanationThe envelope facilitates the release of viruses from infected cells.
#5
Which viral structure is responsible for the transfer of genetic material into host cells?
Viral spike proteins
ExplanationSpike proteins facilitate the transfer of genetic material into host cells.
#6
What is the role of the viral polymerase during the viral replication cycle?
To replicate the viral genome.
ExplanationThe polymerase is crucial for replicating the viral genetic material.
#7
Which of the following viruses is NOT classified as an RNA virus?
Hepatitis B virus
ExplanationHepatitis B virus is a DNA virus, not an RNA virus.
#8
Which of the following is a characteristic of a viroid?
It consists of a short, single-stranded RNA molecule.
ExplanationViroids are composed of short, single-stranded RNA.
#9
Which of the following is a characteristic of prions?
They are composed of protein only.
ExplanationPrions consist solely of protein.
