Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The cytoskeleton of a cell is composed of
A
microtubules and microfilaments
B
microtubules, intermediate filaments, and microfilaments
C
filaments and phospholipids
D
filaments and tubules
Explanation: 

Detailed explanation-1: -It is made up of microtubules, microfilaments and intermediate filaments. Microtubules are formed of tubulin protein which helps in chromosomal movement during cell division. Microfilaments are made up of actin protein and intermediate filaments are made up of keratin, vimentin and desmin proteins.

Detailed explanation-2: -The primary types of fibers comprising the cytoskeleton are microfilaments, microtubules, and intermediate filaments. Microfilaments are fine, thread-like protein fibers, 3-6 nm in diameter. They are composed predominantly of a contractile protein called actin, which is the most abundant cellular protein.

Detailed explanation-3: -The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments. These structures give the cell its shape and help organize the cell’s parts.
