1)Most are between 10 to 300 nm. Some are larger.

2)Life Cycle:

Attachment: attaching to the host cell

Penetration: injecting viron into host

Uncoating: removal of viral protein sheath

Replication: virus takes over host and replicates using    host’s enzymes

Assembly: new viruses are packaged in host
