|
|
|
A virus attaches to the surface of a host cell
|
|
|
The proteins and genetic material start to assemble in the cell
|
|
|
The host cell bursts open, releasing the new viruses
|
|
|
The virus injects its genetic material into the cell
|
Detailed explanation-1: -The final stage is release. Mature viruses burst out of the host cell in a process called lysis and the progeny viruses are liberated into the environment to infect new cells.
Detailed explanation-2: -Egress. The last stage of viral replication is the release of the new virions produced in the host organism. They are then able to infect adjacent cells and repeat the replication cycle.
Detailed explanation-3: -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-4: -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.
