What forms a spindle-shaped structure of protein fibers on which the chromosomes move during nuclear division?
Answer (2)
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.
The spindle-shaped structure of protein fibers on which chromosomes move during nuclear division is called the centrosome, which contains centrioles. These structures organize microtubules to form the mitotic spindle, crucial for chromosome separation during cell division. While centrioles are found in animal cells, plant cells also form spindles, though without centrioles.
