What is the first step in the viral replication cycle?
Attachment
What is the role of the host in viral replication?
To facilitate the replication of the virus
What determines the host range of a virus?
The specificity of the viral receptor
What is the term for the classification of viruses based on their genome type?
Viral classification
What is the primary mechanism of virus penetration into host cells for non-enveloped viruses?
Endocytosis
What is the term for the removal of the viral capsid to release the genome into the host cell?
Uncoating
Where do RNA viruses typically replicate in the host cell?
Cytoplasm
What is the term for the specificity of a virus to infect a particular host or range of hosts?
Host range
What is the function of cellular receptors in the process of viral infection?
To facilitate viral attachment and entry
What is the result of the uncoating process in the viral life cycle?
The release of the genome into the host cell
What is the stage of the virus life cycle where the virus becomes infectious?
Maturation
What is the primary purpose of virus cultivation?
To isolate and identify viruses in clinical samples
What type of viruses are typically released from the host cell by budding?
Evolved viruses
What is the process of packaging viral proteins with the newly replicated viral genome into new virions?
Assembly
What is the result of lysis in viral release?
The host cell dies
Why are viruses cultured in living cells?
Because they are obligate intracellular parasites
Learn about the complex process of virus replication, where all components are produced separately and assembled into intact virons. Discover how viruses are host-specific and have a narrow or broad host range.
