WebVideo transcript. - Let's talk about microtubules in more detail. So, first we'll discuss the structure. So, microtubules are made up of two proteins. The first is called alphatubulin, and the second similar protein is called betatubulin, and the alphatubulin and betatubulin will join together to form a dimer. A dimer's simply when you have two ...

WebSpindle fibres are proteins that pull the chromosomes towards the poles. These spindle fibres are formed during metaphase of mitosis. Centrioles help in cell division. During prophase they move towards the poles and in metaphase the spindle fibres are formed between centrioles and the centromere of the chromosome. Suggest Corrections 2 WebAnswer: Cells cannot divide without spindle fibre. Because, during Anaphase Spindle fibres get attached to the Kinetochore resulting in the pull apart of the sister chromatids of the Chromosomes followed by division of cytoplasm (Cytokinesis) and which is the most important step of cell division....

WebThe other type of muscle spindle sensory fiber, the type II fiber, is principally associated with nuclear chain fibers (Fig. 24.4A; Table 24.1). Its connection with the equatorial region of the target intrafusal fiber has the form of a cluster of thin, radiating branches and is called a secondary ending or flower-spray ending.
