Question
The cytoskeleton includes all of the following except
Correct Answer
Option A is the correct answer.
Detailed Explanation
The cytoskeleton is primarily composed of three types of protein filaments: microfilaments (actin), microtubules (tubulin), and intermediate filaments (various proteins like keratin). Myosin is a motor protein that interacts with actin filaments to cause contraction, but it is not considered a structural component of the cytoskeleton itself.
Hint
Which of these is a motor protein that walks along filaments, rather than a structural filament itself?
