NEET (UG) 2023 — Question 130

Cytoskeleton is an elaborate network of filamentous proteinaceous structures consisting of microtubules, microfilaments and intermediate filaments present in the cytoplasm. It provides mechanical support, maintains the shape of the cell and is involved in cell motility. Protein synthesis is carried out by ribosomes, not by the cytoskeleton. Nuclear division involves the spindle apparatus formed by microtubules during cell division, but it is not listed as a general cytoskeletal function in this context. Therefore, the function carried out by the cytoskeleton among the given options is motility. Hence, the correct answer is B.
