How a virus multiplies inside a host cell
WebViruses invade a host and attach themselves to a cell. As they enter the cell, they release their genetic material. This material forces the cell to replicate the virus, and the virus multiplies. When the cell dies, it releases new viruses, which infect new cells. - Not all viruses destroy their host cell, however. WebStep 2: Penetration: The virus is brought into the target cell. Step 3: Uncoating and Replication: The enveloped virus loses its envelope, and viral RNA is released into the nucleus, where it is replicated. Step 4: …
