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.
spindle fibers A collection of microtubules attached to a centromere during mitosis and meiosis that are responsible for the movement of the chromosomes to opposite poles. Spindle fibers align the chromosomes along the middle of the cell nucleus. The protein fibers formed during prophase of nuclear division; chromosomes attach to these fibers at the centromere. spindle The aggregation of microtubules that is involved in the movement and separation of chromosomes during mitosis and meiosis.
