Detailed explanation-1: -Step 1: Adsorption. Step 2: Penetration. Step 3: Replication. Step 4: Maturation. Step 5: Release. Step 6: Reinfection. 09-Apr-2022
Detailed explanation-2: -Lytic cycle Attachment: Proteins in the “tail” of the phage bind to a specific receptor (in this case, a sugar transporter) on the surface of the bacterial cell. Entry: The phage injects its double-stranded DNA genome into the cytoplasm of the bacterium.
Detailed explanation-3: -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.
