Routing Protocol Definition. A routing protocol is a set of rules used by routers to determine the most appropriate paths into which they should forward packets towards their intended destinations.
Spindle fibers are protein structures that form early in mitosis, or cell division. They consist of microtubules that originate from the centrioles, two wheel-shaped bodies located in the centromere area of the cell. The centromere is also known as the microtubule organizing center.
Lesson Summary. The mitotic spindle is a structure composed of microtubules which segregates chromosomes into the daughter cells during mitosis. A microtubule is a rope-like component of the cytoskeleton. The centrosome is an organelle that serves as a microtubule organizing center during cell division.n astral microtubule is a short microtubule which emanates from the centrosome and serves to accurately position the mitotic spindle within the cell. A kinetochore microtubule is a microtubule which attaches to the kinetochore and positions the chromosomes during mitosis.
