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.
The centromeres spit and the sister chromatids are pulled apart to opposite poles of the cell. Telophase: the Fourth phase of mitosis. Spindle fibers begin to break down, the nucleus reappears and new nuclear envelope forms around each set of chromosomes. A new membrane begins to form between the two new nuclei.
