Verified step by step guidance1
Understand the sequence of stages in the viral replication cycle: Attachment (adsorption), Penetration, Uncoating, Replication, Assembly, and Release.
Identify that the first step involves the virus recognizing and binding to specific receptors on the host cell surface, which is called Attachment (adsorption).
Recognize that Penetration follows Attachment, where the virus enters the host cell either by fusion or endocytosis.
Note that Uncoating occurs after Penetration, where the viral capsid is removed to release the viral genome inside the host cell.
Conclude that Assembly happens later in the cycle, where new viral particles are put together before being released.
