30+ Microtubules In Animal Cell Diagram PNG. Microtubules play a key role in forming the mitotic spindle, also called the spindle apparatus. Several proteins are bound to microtubules namely dynein and kinesin.
Microtubules are one type of filament protein in the cytoskeleton. In most animal cells, during g1 and g0 phases of the cell cycle, there is one centrosome per cell found close to the nucleus. The left image shows the tube's molecular structure.
They are made out of subunits called tubulin.
Microtubules are also the structural elements of flagella, cilia, and centrioles (the latter are the centrosome's two perpendicular bodies). They move vesicles, granules, organelles like mitochondria, and chromosomes via special attachment proteins. The left image shows the tube's molecular structure. Animal cell lacks a cell wall.
