Lytic and Lysogenic cycles are the method of viral multiplication. Lytic cycle, comparitively more common, is a method of viral multiplication wherein the virus attacks a host cell. It destroys the host cell totally by feeding on the metabolism of the host in order to multiply. Lysogenic cycle, not a common method of viral reproduction, majorly is dependant on the lytic cycle. In this method, the virus unites its genetic details with that of the host, turning dormant and lets the host to reproduce while continuing its regular activities. Although similar at times, understanding the difference between lytic cycle and lysogenic cycle is important.
Lytic vs Lysogenic Cycle
|Lytic Cycle||Lysogenic Cycle|
|The DNA of the virus doesn’t integrate into the host DNA||The DNA of the virus integrates into the host DNA|
|Host DNA hydrolyzed||Host DNA not hydrolyzed|
|Absence of prophage stage||Presence of prophage stage|
|DNA replication of virus takes place independently from the host DNA replication||DNA replication of the virus takes place along with the host DNA replication|
|Occurs within a short period of time||Takes time|
|Symptoms of viral replication are evident||Symptoms of viral replication not evident|
|Genetic recombination in the host bacterium not allowed||Genetic recombination in the host bacterium allowed|
|The cellular mechanism of the host cell is totally undertaken by the viral genome||The cellular mechanism of the host cell is somewhat disturbed by the viral genome|
The main difference between the lysogenic cycle and lytic cycle is their influence on the host cell. At CoolGyan’S, learn more differences like the difference between replication and transcription.
