Generally, lytic enzymes destroy the host cell. With the HIV virus, release does not necessarily lyse the cell. These become prophages and are reproduced every time that the host cell enters the mitotic cycle. Sometimes temperate viruses become lytic spontaneously. Lytic cycle of rubella virus Virus attaches to host cell.
Plasma membrane surrounds the virus and an endosomal vesicle forms.
The envelope of the virus fuses with the membrane and the vesicle. The virus is released into the host's cytoplasm Viral nucleic acid separates from its capsid Nucleic acid enters host nucleus and replicates Transcription into mRNA Host ER directed by mRNA to synthesize glycoproteins and capsid proteins plus proteins of the viral envelope. Vesicles transport glycoproteins to plasma membrane of cell. New viruses assemble and are released from host cell after being enveloped by host's modified plasma membrane. The virus enters the host cytoplasm and the capsid is removed.
