The thickest are the microtubules (20 nm in diameter) which consist primarily of the tubulin protein. The centrosome is a part of almost all plant and animal cells that includes a pair of centrioles, which are structures consisting of an array of nine microtubule triplets. The prefix "kineto-" means "move," and the suffix "-chore" also means "move or spread." Each chromosome has two kinetochores. Microtubules are also responsible for the separation of chromosomes during cell division. Microtubules, the third principal component of the cytoskeleton, are rigid hollow rods approximately 25 nm in diameter. Size.

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. For this reason, they are located near the nucleus. Microtubule nucleation occurs spontaneously in purified tubulin solutions, and molecular intermediates between tubulin dimers and microtubules have been identified. 3.2 Definition of Microtubule Classes, Geometry Definition. Microtubule length is quite variable. Microtubule definition is - any of the minute tubules in eukaryotic cytoplasm that are composed of the protein tubulin and form an important component of the cytoskeleton, mitotic spindle, cilia, and flagella. Register Using the zebrafish, the authors showed the progressive establishment and maintenance of planar cell polarity in the zebrafish floorplate. Here are 4 tips that should help you perfect your pronunciation of 'microtubules': Break 'microtubules' down into sounds : say it out loud and exaggerate the sounds until you can consistently produce them. Views expressed in the examples do not represent the opinion of Merriam-Webster or its editors.
