Question

Which of the following cytoskeletal fibers is the largest in diameter?

A) microtubules
B) actin filaments/microfilaments
C) intermediate filaments
D) nuclear lamins
E) keratin filaments

Answer 1

A) microtubules

Step-by-step explanation:

The diameter of the cytoskeletal fibers are as follows -

• Microtubules about 25 nano meters

• actin filaments/micro filaments is about 7 nano meters
• intermediate filaments about 8 to 10 nano meters

Hence ,

From the above data , Microtubules have the largest diameter , it is made up of tubulin proteins which are arrange in the form of a straw - like tube which is hollow from inside , and each of the tubuline protein consists of two sub units i.e. alpha - tubuline and the beta - tubuline .
