Detailed Solution

Both (A) and (R) are true and (R) is the correct explanation of (A).

Protein synthesis primarily occurs in dendrites and the cell body (soma) of neurons, where ribosomes and rough endoplasmic reticulum (RER) are abundant, while axons generally lack these structures. Nissl granules, which are specialised regions of RER, involved in protein synthesis, are present in dendrites and the cell body but not in axons.
