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 main difference between interphase and the first stage of mitosis is that the chromatin is diffuse and unorganized, according to Nature Education. Prophase, the first stage of cell division, occurs when the chromatin coils and condenses to form the chromosomes. During this stage, the chromosomes are visible under a microscope showing the two chromatids (strands) connected by a centromere.
