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.
In telophase, the spindle disappears, and a nuclear membrane forms around the chromosomes at each end of the cell. The cytoplasm of the dividing cell begins to separate during mitosis and ends after division of the nucleus is complete. During interphase, the daughter cells develop and the chromosomes duplicate.
