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.
Interphase is followed by meiosis I and then meiosis II. Meiosis I separates homologous chromosomes, each still made up of two sister chromatids, into two daughter cells, thus reducing the chromosome number by half. During meiosis II, sister chromatids decouple and the resultant daughter chromosomes are segregated into four daughter cells.
