Detailed explanation-1: -In a lytic cycle, the virus introduces its genome into a host cell and initiates replication by hijacking the host’s cellular machinery to make new copies of the virus. Once infection is complete, the newly replicated and assembled virus particles are released through lysis of the host cell into the surrounding waters.
Detailed explanation-2: -The lytic cycle, which is also commonly referred to as the “reproductive cycle” of the bacteriophage, is a six-stage cycle. The six stages are: attachment, penetration, transcription, biosynthesis, maturation, and lysis.
Detailed explanation-3: -In the lytic cycle, a phage acts like a typical virus: it hijacks its host cell and uses the cell’s resources to make lots of new phages, causing the cell to lyse (burst) and die in the process.
Detailed explanation-4: -In the lytic cycle (Figure 2), sometimes referred to as virulent infection, the infecting phage ultimately kill the host cell to produce many of their own progeny.
