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.
Prophase I -Centrioles move to opposite ends. Spindle fibers form, and chromosomes condense. Metaphase I- Chromosomes attach to the spindle fibers and line up at the equator of the cell. Anaphase I - Chromosomes are spereated by spindle fiber and chromatids go to the poles.
