Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is the correct order of the steps of the lytic cycle?
A
Adsorption; replication; entry; assembly; release
B
Attachment; entry; replication; assembly; release
C
Attachment; entry; assembly; replication; exit
D
Entry; adsorption; replication; assembly; release
Explanation: 

Detailed explanation-1: -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-2: -The lytic cycle involves four steps: infecting a host (an action called exposure), injecting a cell with the virus’s genetic material, using the cell’s metabolic engines to create new viruses, and finally, weakening the cell walls until the host cell lyses, or bursts open from excessive internal pressure.

Detailed explanation-3: -Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release. During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it.

Detailed explanation-4: -The viral life cycle can be divided into several major stages: attachment, entry, uncoating, replication, maturation, and release.
