Detailed explanation-1: -This process of host cell takeover is known as “molecular hijacking.” When a virus replicates it has to build entire viral particles and it has to not only make the proteins that comprise the viral capsid (and enclose it with an envelope), but it must also replicate its genetic material.

Detailed explanation-2: -Once a virus gets into a host’s body, it travels along the surfaces of cells until its proteins begin to bind with receptors on the cells. The virus and the cells then fuse, allowing the DNA or RNA inside the virus to enter the cells, where it begins to reproduce.

Detailed explanation-3: -The virus’s genome is uncoated from the protein and injected into the host cell. Then the viral genome hijacks the host cell’s machinery, forcing it to replicate the viral genome and produce viral proteins to make new capsids. Next, the viral particles are assembled into new viruses.

Detailed explanation-4: -During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it. During uncoating, replication, and assembly, the viral DNA or RNA incorporates itself into the host cell’s genetic material and induces it to replicate the viral genome.

Detailed explanation-5: -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.
