Explanation:
The viral life cycle starts with its adsorption to the host cell and is mediated by the interaction between receptors present on the cell surface of the host and surface ligands of the virus.
This is followed by the entry of the viral genome or the whole nucleocapsid into the host cell and is known as penetration. Once inside the host cell, the viral genes are expressed and there is the synthesis of viral proteins and nucleic acids.
The newly formed capsid proteins and nucleic acids are assembled into virions which in turn are released from the host cell by one of the several mechanisms such as budding.
Prokaryotes don't have a nuclear envelope they have no nucleus.
