Techopedia explains Routing Protocol. Most Internet Protocol (IP) networks use the following routing protocols: Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP): These provide interior gateway routing through path or distance vector protocols.
As mitosis progresses, the microtubules attach to the chromosomes, which have already duplicated their DNA and aligned across the center of the cell. The spindle tubules then shorten and move toward the poles of the cell. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell.
A cell when undergoes the process of cell division there are structures known as spindle fibres that are required to pull the chromosomes off to the poles of the cell so that it can be segregated into the cells properly while division. These spindle fibres are made of microtubules that are protein molecules constituting the cytoskeleton of a cell.
