What form a spindle shaped structure of protein fibres on which the chromosomes move during nuclear division? 



Answer :

Function of centrioles

An organelle that forms a spindle-shaped structure of protein fibers on which the chromosomes move during nuclear division are called the centrioles. Centrioles are part of the animal cell organelles. Hence, they are a small part of the microtubules organized and set in a particular course. Microtubules include 9 sets. Centrioles contain a cylindrical structure, packed with protein which is described as tubulin. Found mostly in eukaryotic cells beside the nucleus.
