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. Microfilaments
• B. lntermediate filaments
• C. Lamins
• D. Microtubules

Answer 1

The correct option is A Microfilaments

• The eukaryotic cell is composed of a network of protein fibres that is known as the cytoskeleton.
  
• It is responsible for the movement of organelles around the cytoplasm (organelles are attached to the cytoskeleton).
• Microfilaments are solid linear cytoskeletal (thinnest cytoskeleton) elements which have a diameter of 6 nm and made up of a single type of monomer.
  
• It is also known as actin filaments and is made up of actin protein.
• So, the correct answer is 'Microfilaments'.
