Question

which part of the virus allows it to dock onto the host cell?
○ capsid
○ nucleocapside
○ dna
○ spike

Explanation:

To determine the part of the virus that allows it to dock onto the host cell, we analyze each option:

• Capsid: The protein shell of a virus, mainly for protecting the genetic material, not for docking.
• Nucleocapside: Consists of the viral genome and capsid, not directly involved in docking to the host cell.
• DNA: The genetic material of some viruses, responsible for encoding viral proteins, not for docking.
• Spike: Viral surface proteins (spikes) bind to specific receptors on the host cell, enabling the virus to dock onto the host cell.

Answer:

D. spike
