|
Virus injects its DNA/RNA into the host
|
|
|
Virus DNA is copied and assembled into new viruses
|
|
|
Virus DNA is integrated into cell’s DNA
|
|
|
New viruses burst out of the cell
|
Detailed explanation-1: -So the correct option is ‘ Phage DNA integrates with host DNA’.
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: -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 the attachment phase, the virus attaches itself to the bacterium. During penetration, the virus penetrates the cell with the help of enzymes and supports the entry of viral genome into the host cell. Hence, Attachment and penetration in lytic cycle follows attachment of virus and release of DNA into host cell.
