None of the above

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: -The lysogenic cycle, or non-virulent infection, involves the virus assimilating its genome with the host cell’s genome to achieve replication without killing the host.
Detailed explanation-3: -In the lytic cycle, the virus attaches to the host cell and injects its DNA. Using the host’s cellular metabolism, the viral DNA begins to replicate and form proteins. Then fully formed viruses assemble. These viruses break, or lyse, the cell and spread to other cells to continue the cycle.
Detailed explanation-4: -The prophage takes an antibiotic resistance gene with it and is packaged with the newly synthesized viral DNA. Lysogenic viral DNA which has integrated into the host genome is referred to as. a prophage.
