Question

Microtubule play important role in the assembly and disassembly of spindle structures during cell division

Answer 1

Yes, microtubules of endoplasmic reticulum is act very important role i.e, It provide support to cell.

Thank you.

Answer 2

Microtubules are empty chambers comprised of rehashing protein structures, explicitly dimers of alpha and beta-tubulin

Microtubules

• Microtubules are empty chambers comprised of rehashing protein structures, explicitly dimers of alpha and beta-tubulin (likewise alluded to recorded as a hard copy as ɑ-tubulin and β-tubulin).
• Dimers are edifices of two proteins. ɑ-tubulin and β-tubulin tie to one another to shape a dimer, and afterwards numerous units of these dimers tie together, continuously rotating alpha and beta, to frame a chain called a protofilament.
• Microtubules assume a key part in shaping the mitotic shaft, likewise called the shaft contraption. This is a construction that is shaped during mitosis (cell division) in eukaryotic cells.
• The mitotic shaft arranges and isolates chromosomes during cell division with the goal that the chromosomes can be parceled into two separate little girl cells. Its parts incorporate microtubules, the MTOC, and microtubule-related proteins (MAPs).
