When it comes to virus multiplication, viral budding, or exocytosis, occurs during

Viral budding or exocytosis occurs during the release stage of the viral replication cycle. Here are the steps:

1. Attachment: The virus attaches itself to a host cell.

2. Penetration: The virus penetrates the host cell and injects its genetic material into it.

3. Uncoating: The viral capsid is removed, releasing the viral genetic material inside the host cell.

4. Replication: The host cell's machinery is used to replicate the viral genetic material and to produce viral proteins.

5. Assembly: New viral particles are assembled within the host cell.

6. Release: The newly formed viruses are released from the host cell. This is where viral budding or exocytosis occurs. The virus uses a portion of the host's cell membrane to envelope itself and bud off from the host cell. This process allows the virus to leave the host cell while killing or damaging it.
