Flashcards on Viruses and Prions
Click on the flashcard to see the answer
What is a virus?
A small infectious agent that replicates only inside the living cells of other organisms.
What are prions?
Abnormal proteins that can cause other proteins to become misshapen and malfunction.
How do viruses replicate?
They hijack the cellular machinery of a host organism to produce more copies of themselves.
What is the main difference between viruses and prions?
Viruses are composed of genetic material (DNA or RNA) enclosed in a protein coat, while prions are just misfolded proteins.
Can viruses and prions infect humans?
Yes, both viruses and prions can infect humans and cause diseases.
What is an example of a viral infection?
Influenza (flu)
Which disease is caused by prions?
Creutzfeldt-Jakob disease (CJD)
Can prions be destroyed by usual cooking methods?
No, prions are very resistant to heat and are not destroyed by usual cooking methods.
How can viruses be prevented?
Vaccination, practicing good hygiene, and avoiding close contact with infected individuals.
What is the structure of a virus?
A virus typically consists of a nucleic acid core (DNA or RNA) surrounded by a protein coat.
Are prions considered living organisms?
No, prions are not considered living organisms as they lack genetic material.
What is an example of a prion disease in animals?
Bovine spongiform encephalopathy (BSE or mad cow disease)
Can antibiotics kill viruses or prions?
No, antibiotics are only effective against bacterial infections and have no effect on viruses or prions.
How do prions cause diseases?
Prions induce other proteins to adopt the misfolded prion shape, leading to tissue damage and neurological symptoms.
What is the mode of transmission for most viruses?
Through respiratory droplets from coughing or sneezing, or by touching contaminated surfaces and then touching the face.
