BIOLOGY
Asked by Richard

What are the differences between a lytic infection and a lysogenic infection?

Both types of infection are modes of viral reproduction. During a lytic cycle, a virus injects its genetic material to the host's DNA, therefore the host cell can now produce copies of the virus. After synthesis and assembly of the new viruses, they release themselves to infect new cells; this happens by destroying the new cell (lysis originates from the Greek word for destruction,decomposition). The lysogenic cycle is quite similar to the lytic one, except for the "dormant" phase. When the virus injects it genetic material in the host's DNA, this stays inactive. When the host cell divides, the coral genome is also replicating itself, while dormant. The lysogenic cycle can also shift to the lytic cycle. An example of this could be seen in viruses that lie dormant for years and "attack" after the host's immune system is compromised or suppressed.
