Spindle apparatus
Videos
In cell biology, the spindle apparatus is the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the

Microtubule
Videos
Microtubules are biopolymers of tubulin that form part of the cytoskeleton to provide structure and shape to a eukaryotic cell. Microtubules can be as long as 50 micrometres, as wide as 23 to 27 nm an

…produces gametes with half the number of chromosomes of the parent cell. Besides chromosomes, the spindle apparatus is composed of hundreds of proteins. Microtubules comprise the most abundant components of the machinery. Attachment of microtubules to chromosomes is mediated by kinetochores, which actively monitor…
Components of the eukaryotic cytoskeleton include: nuclei (blue), microtubules (green), and actin filaments (red).

Tubulin Infographic
Microtubules are one of the cytoskeletal filament systems in eukaryotic cells. The microtubule cytoskeleton is involved in the transport of material within cells, carried out by motor proteins that move on the surface of the microtubule.
