Lytic or Lysogenic cycle. 4C

Lytic Cycle

In the Lytic state, viral copies are made and sent back into the environment. First the virus attaches itself to the host, Bacteria. Then the virus inserts its DNA into the Bacteria. The virus takes over the cells machinery. Then the virus reproduces, so the cell gets overcrowded and bursts. When the cell wall bursts, it is called Lysing and the new viruses are released. Which means the host is destroyed.

Lysogenic Cycle

In the Lysogenic Cycle, there is no pathology which means cause and effect of diseases. First the virus binds to the bacteria (host). Then the virus inserts DNA into host. The viral DNA then gets incorporated into the hosts chromosomes. Viral DNA is replicated along with chromosomal material.


In the Lytic Cycle:

  • The viral DNA destroys the cells DNA, and takes over cell functions and destroys the host.
  • replicates within the cell
  • symptoms of viral infection

In the Lysogenic Cycle:

  • Viral DNA merges with cell but does not destroy it
  • Doesn't replicate within the cell, it just exists inside it
  • no symptoms of viral infection
