Answer :
Final answer:
The lytic pathway is the method by which viruses kill host cells as they replicate. It involves several stages, from attachment to the eventual lysis of the host cell, which releases new viruses. This is different from the lysogenic pathway, where the host cell is not immediately destroyed.
Explanation:
Understanding Viral Replication and Cell Death
Viruses are fascinating entities that require a host cell to replicate. Among the pathways through which viruses affect host cells, the lytic pathway is the most notable method by which they cause cell death. In this process, the virus hijacks the host's cellular machinery to reproduce itself, ultimately leading to the destruction of the host cell.
How the Lytic Pathway Works
The lytic pathway involves several key steps:
- Attachment: The virus attaches to the surface of the host cell.
- Pentration: The virus injects its genetic material into the host cell.
- Replications: The host cell's machinery is used to replicate the viral components.
- Assembly: New virus particles are assembled within the host cell.
- Lysis: The host cell eventually bursts, releasing new viruses to infect other cells.
This mechanism is in contrast to the lysogenic pathway, where the viral DNA integrates into the host genome without immediately killing the host. Understanding the differences between these pathways is crucial for comprehending viral infections and developing treatment strategies.
