Lytic animal viruses

Definition

Lytic animal viruses are viruses that infect animal cells and cause the lysis (destruction) of the host cell during their replication cycle. This results in the release of new viral particles.

5 Must Know Facts For Your Next Test

1. The lytic cycle consists of attachment, penetration, biosynthesis, maturation, and release.
2. During the lytic cycle, viral DNA is not integrated into the host genome.
3. Lysis of the host cell releases newly formed virions to infect neighboring cells.
4. Symptoms of viral infections can be due to cell destruction caused by lytic cycles.
5. Examples include bacteriophages like T4 and animal viruses like Influenza virus.
