For attachment, the rabies virus binds to a:
Correct answer: C. Acetylcholine receptor
- A. Complement receptor
- B. Integrin ICAM-1
- C. Acetylcholine receptor
- D. Epidermal growth factor receptor
Explanation
To clarify, the attachment of the rabies virus to host cells involves interactions between viral glycoproteins and specific receptors, and in the case of the rabies virus, one of the receptors used for attachment is the nicotinic acetylcholine receptor (nAChR). This receptor is normally associated with nerve signal transmission but is repurposed by the virus for attachment, facilitating its entry into host cells.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
