The role of the capsid in the viral structure includes: 1. facilitating viral replication ...

Correct Answer: 4
Rationale 1: This is the role of the viral proteins.
Rationale 2: This does not describe the role of the capsid.
Rationale 3: This does not describe the role of the capsid.
Rationale 4: The role of the capsid is to help the virus attach to the cell membrane of the host.
Global Rationale: The virus is surrounded by a protein coat or capsid, which helps to protect it from the surrounding environment. The structural proteins or glycoproteins that comprise the capsid are arranged in distinct, repeating subunits. These proteins help the virus attach to the cell membrane of its host. Viral proteins facilitate replication of DNA or RNA. Capsids do not allow for release of the viral infection from the host or trigger body defenses to remove the invader.
