5 stages of animal virus

1. Viral Attachment or Adsorption to the Host Cell

2. Viral Entry into the Host Cell

3. Viral Movement to the Site of Replication within the Host Cell and Release of the Viral Genome from the Remainder of the Virus.

4. Viral Replication within the Host Cell

5. Viral Assembly or Maturation within the Host Cell

6. Viral Release from the Host Cell

Different types:

ENVELOPED VIRUS: A virus consisting of nucleic acid within either a helical or polyhedral core and surrounded by an envelope. The envelope is usually derived from a host cell membrane by budding.

NAKED VIRUS: A naked or nucleocapsid virus lacks an envelope and consists of only a genome and a capsid.
