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 three phases of interphase following mitosis are: the the G 1 growth phase, the S phase or synthesis phase, which is when DNA is replicated, and the G 2 growth phase. Although the synthesis of nuclear DNA is restricted to the S phase, replication of cellular components can occur throughout the cell cycle (mostly being limited to G 1, S, and G 2).
