16 Questions
What is a characteristic that distinguishes eukaryotic cells from prokaryotic cells?
Presence of a nucleus
What is the primary function of the replication complex in viral replication?
To make more RNA
What is the purpose of the enzyme that helps the virion enter the host cell?
To release the viral RNA into the host cell
What is the main difference between prokaryotic and eukaryotic cells in terms of their internal structure?
Eukaryotic cells have a more organised internal structure
What is the role of the Golgi apparatus in the viral replication cycle?
To assemble new virions
What is the characteristic that defines viruses as being 'alive' or 'not alive'?
Ability to cycle between being alive and not alive
What is the primary reason why viruses require larger cells to function?
To hijack cellular machinery for replication
What is the role of the ACE2 protein in the SARS-CoV-2 viral cycle?
It acts as a receptor for the spike protein
What is the primary advantage of compartmentalization in eukaryotic cells?
It enables cells to perform specialized functions more efficiently
What is the primary difference between prokaryotic and eukaryotic cells in terms of their metabolism?
Eukaryotes have a more complex metabolism
What is the function of the RNA translated into proteins by the host cell's machinery?
It forms a replication complex to produce more RNA
What is the characteristic that distinguishes viruses from other forms of life?
They cycle between being alive and not alive
What is the primary function of the cell surface proteins in the context of viral infection?
They provide a binding site for the virus
What is the primary advantage of having a nucleus in eukaryotic cells?
It protects the genome and DNA sequences
What is the primary characteristic that distinguishes prokaryotic cells from eukaryotic cells?
The presence or absence of a nucleus
What is the role of the lipids in the membranes surrounding prokaryotic and eukaryotic cells?
They form the structure of the cell membrane
This quiz covers the basics of viruses, including their structure, function, and how they interact with cells. Learn about how viruses hijack cellular processes to replicate and the role of cell surface proteins in this process.
