Question

The solid linear cytoskeletal elements having a diameter of 6 nm and made up of a single type of monomer are known as

(a) microtubules

(b) microfilaments

(c) intermediate filaments

(d) lamins

Answer 1

Correct option  (b) microfilaments

Explanation

Microfilaments (actin filament) are the thinnest filaments of the cytoskeleton.they are found in the cytoplasm of the eukaryotic cell.

They constitute the cytoskeleton through which the cells acquire shape their diameter is approximately 6 nm (avg.) These are the polymer of actin sub- units.
