What is the life cycle of a virus called?

A virus is RNA and DNA surrounded by protein. A virus can not live alone without a host cell. The life cycles are: attachment, penetration, uncoating, replication and release. During the release process, viruses may escape from the host cell by causing cell rupture viruses typically "bud" from the host cell. During the budding process, a virus acquires the phospholipid envelope containing the embedded viral glycoproteins.
