Shapes & Structures
All animal cell viruses contain these two parts.
What are the capsid and the genome?
When a virus infects a bacterium, it injects this into the cell.
What is its genome or viral nucleic acid?
Viruses that can lead to cancer when they infect cells.
What are oncoviruses?
This coating surrounds the genome.
What is the capsid?
The larger class of viruses that SARS-CoV-2 belongs to.
What are coronaviruses?
These infectious protein particles do not contain DNA or RNA.
What are prions?
This structure will contain both viral spike proteins and some host cell proteins.
What is the envelope?
When animal cell viruses lay dormant in cells they are called this type of viruses.
What are latent viruses?
This viruses causes chickenpox and shingles.
What is varicella zoster?
This is one way the genes of viruses and cells are the same.
What is they can mutate and change over time?
A double-stranded DNA virus can use this enzyme to copy its genome.
What is DNA Polymerase?
When bacteriophage infect a cell but do not form more virions.
What is the lysogenic cycle?
Mad Cow Disease, Scrapie, Kuru and CWD all have this in common.
What are prion diseases?
An ability to infect a wide range of organisms or cell types (such as the rabies virus), means a virus has a large one of these.
What is a host range?
If a virus does not have a double-stranded DNA genome, it will need some of these to replicate.
What are unique viral enzymes or polymerases?
During the lysogenic cycle, the viral DNA does this.
What is inserts itself into cell & forms the provirus.
This the most effective way to prevent the spread of a virus.
What is a vaccination?
Which step of the viral replication cycle can be blocked by antibodies?
What is attachment (or penetration)?
