|
|
Virus goes in and leaves the host cell
|
|
|
Virus quickly kills the host cell
|
|
|
Virus inject the nucleic acid into the host cell, and the nucleic acid integrates into the host cell DNA, and stay dormant for a long time
|
|
|
Bacteria injects DNA into a host cell
|
Detailed explanation-1: -The lysogenic cycle: The phage infects a bacterium and inserts its DNA into the bacterial chromosome, allowing the phage DNA (now called a prophage) to be copied and passed on along with the cell’s own DNA.
Detailed explanation-2: -During the lysogenic cycle, the virus genome is reversibly integrated into the host chromosomes or replicates as a plasmid (or episome) in such a way that it does not lead to virus progeny production.
Detailed explanation-3: -Lysogenic cycle Following the injection of the phage DNA into the host cell, it integrates itself into the host genome, with the help of phage-encoded integrases, where it is then termed a prophage.
Detailed explanation-4: -Like the lytic cycle, in the lysogenic cycle the virus attaches to the host cell and injects its DNA. From there, the viral DNA gets incorporated into the host’s DNA and the host’s cells.
