Which step of the virus replication cycle comes immediately after penetration?

1. A productive infection runs through six steps in a fixed order. 2. The order is attachment, penetration, uncoating, replication, assembly, and release. 3. Penetration is the second step, so uncoating is the one that follows it. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 21 "Viruses", section 21.2 Virus Infections and Hosts_
