Question

choose the phrase that best describes the role of viral surface proteins or spikes. multiple choice provide means for viruses to exchange nucleic acid provide means of attachment to host cell surface enable replication of the viral nucleic acid allow viruses to bind to each other inject viral nucleic acid into host cell

Explanation:

Viral surface proteins or spikes are crucial for the initial step of viral - host interaction. They specifically bind to receptors on the host cell surface, allowing the virus to attach and then potentially enter the cell. They do not directly enable nucleic - acid exchange between viruses, viral nucleic - acid replication, virus - to - virus binding, or injection of viral nucleic acid into the host cell.

Answer:

Provide means of attachment to host cell surface
