Assembly & release.
Verified step by step guidance1
Understand the lytic cycle: The lytic cycle involves the virus attaching to the host cell, injecting its genetic material, replicating its components, assembling new virus particles, and then lysing the host cell to release the new viruses.
Understand the lysogenic cycle: In the lysogenic cycle, the virus also attaches to the host cell and injects its genetic material, but instead of immediately replicating, the viral DNA integrates into the host cell's genome and replicates along with it until it is triggered to enter the lytic cycle.
Identify common steps: Both cycles begin with the virus attaching to the host cell and injecting its genetic material, which are the steps of attachment and genome entry.
Consider replication and synthesis: In the lytic cycle, replication and synthesis occur immediately after genome entry, while in the lysogenic cycle, these processes are delayed until the virus enters the lytic phase.
Compare assembly and release: These steps are part of the lytic cycle where new virus particles are assembled and released, but they do not occur in the lysogenic cycle until it transitions to the lytic cycle.
