Question

what is microtubular structure?​

Answer 1

Answer:

Microtubules are the largest cytoskeletal filaments in cells, with a diameter of 25 nanometers. They are made out of subunits called tubulin. Each tubulin subunit is made up of one alpha and one beta tubulin that are attached to each other, so technically tubulin is a heterodimer, not a monomer. As you can see, it really does look like a tube, hence the name micro'tubule.'

In a microtubule structure, tubulin monomers are linked both at their ends and along their sides (laterally). This means that microtubules are quite stable along their lengths. Imagine that you have some plastic building blocks that are all identical and can attach to each other both at their ends and laterally. If you arranged them into a microtubule structure, and then wanted to take the structure apart, you can imagine that it would be really hard to take it apart somewhere in the middle, because how would you get the first block out? If you wanted to take it apart, you'd have to start at the ends. And indeed, this is how microtubules are assembled and disassembled, only from their ends
