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.
NONDISJUNCTION: when 2 homologous chromosomes move to the same pole during meiosis. One daughter cell will be missing one chromosome while the other will have an extra chromosome. TRISOMY: the gamete with 24 chromosomes joins with a normal gamete (23) to form a zygote with 47 chromosomes.
