Detailed explanation-1: -During lytic infection, a virus enters the host cell, makes a copy of itself, and causes the cell to burst, or lyse. In the video Virus Lytic Cycle, a bacteriophage, which is a virus that infects and replicates within a bacterium, attaches itself and infects the host cell.
Detailed explanation-2: -In a lytic cycle, the virus introduces its genome into a host cell and initiates replication by hijacking the host’s cellular machinery to make new copies of the virus. Once infection is complete, the newly replicated and assembled virus particles are released through lysis of the host cell into the surrounding waters.
Detailed explanation-3: -The first stage is entry. Entry involves attachment, in which a virus particle encounters the host cell and attaches to the cell surface, penetration, in which a virus particle reaches the cytoplasm, and uncoating, in which the virus sheds its capsid.
