10 Questions
What are the main components of a virion that allow it to bind to its host cell and inject its genetic material?
Genetic material, capsid, envelope, and membrane proteins
If a virus lacks certain proteins that make it infectious, even though the genetic material is present, what term is used to describe these viral particles?
Prions
Which of the following is NOT a possibility for a virus genome according to the text?
Triple-stranded RNA (tsRNA)
Why do RNA viruses need to encode RNA polymerase?
To assist in the replication of their RNA genome within host cells
Why are viruses considered parasites?
Because they rely on the host cell's machinery for replication
Which of the following is a characteristic of virus proteins mentioned in the text?
May have overlapping genes and genes within genes
What is the function of an envelope in a virion?
To facilitate attachment to the host cell
Which of the following is NOT mentioned as a characteristic of virus genomes according to the text?
'M' shaped structure
What role do host cell proteins play in virus reproduction?
Host cell proteins assist in producing new virions.
Why are virus proteins considered multifunctional?
Because each protein can perform multiple enzyme activities.
