Question
Chapter 8.5, Problem 3MQ
Summary Introduction
The lytic cycle of the virus replication starts from the attachment of the virus on the surface of the host cell. Then the genome of the virus is inserted into the host cell and then the virus gets replicated. The host genome and the viral genome has certain restriction and modification system for protection against the immune system.
