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.
Now, during metaphase â the second stage of mitosis in the eukaryotic cell cycle â the chromosomes, pulled by the spindle fibers, line up along the middle of the cell, halfway between the centrosomes on an imaginary plane called the metaphase (or equatorial) plate. The chromosomes are now maximally condensed.
