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.
During the telophase stage of mitosis, each set of chromosomes segregates to the ends of the dividing cell, and the spindle fibers depolymerize and disappear, as do the centrioles. The cell then divides into two identical daughter cells.
