❓ Frequently Asked Questions
Q: What are the basic steps of viral replication?
A: Viral replication typically involves attachment, penetration, uncoating, replication, assembly, and release. Each step is crucial for the virus to successfully multiply inside the host cell.
Q: How do viruses attach to cells?
A: Viruses attach to cells via specific receptor proteins on the cell surface that bind to viral proteins. This interaction determines the virus’s host range and tissue tropism.
Q: What happens during viral uncoating?
A: Uncoating is the process where the viral capsid disassembles, releasing the viral genome into the host cell’s cytoplasm or nucleus for replication.
Q: How does viral assembly occur?
A: Viral assembly involves the packaging of newly synthesized viral genomes into new capsid proteins. This typically occurs in specific locations within the host cell.
Q: What are the different types of viral release?
A: Viruses can be released from the host cell via lysis (bursting the cell) or budding (enveloping themselves in the cell membrane). Lysis kills the host cell, while budding allows the cell to survive longer.
