The viral process of attaching to a host cell receptor prior to infecting the cell is called:
A
Penetration
B
Adsorption
C
Assembly
D
Uncoating
Verified step by step guidance1
Understand the viral infection process, which involves several key stages: attachment (adsorption), penetration, uncoating, replication, assembly, and release.
Identify the stage where the virus specifically binds to the host cell's surface receptors. This is the initial step that allows the virus to recognize and attach to a suitable host cell.
Recall that the term for the virus attaching to the host cell receptor is 'adsorption'. This is a specific interaction between viral surface proteins and host cell receptors.
Differentiate adsorption from other stages: penetration is the entry of the virus into the cell, uncoating is the removal of the viral capsid to release genetic material, and assembly is the formation of new viral particles.
Conclude that the correct term for the viral process of attaching to a host cell receptor prior to infection is 'adsorption'.
