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 injects its genetic material into the host cell.

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: This is the stage where viral budding or exocytosis occurs. The newly formed viruses are released from the host cell, either by causing the cell to burst, or by budding off through the cell membrane. This process allows the virus to spread and infect other cells.
