The terms caudal and inferior are synonymous, meaning "away from the head end or toward the lower part of a structure or the body; below." The umbilicus is caudal (inferior) to the chin.
It selectively controls what goes in and out of the cell
DNA fulfills the function of replicating itself, which is a process in which identical copies of each molecule of the same are made. This replication is essential so that the genetic data can be transferred from one generation to the next, constituting the basis of the inheritance.
<span>The mechanism is given by separating the two chains of the helix from it, to serve as a template in the formation of new chains, which are called messenger RNA. Which are the result of two molecules equal to the first. This replication is called semi conservative, since each molecule resulting from the replication has one chain of the mother molecule and another newly created one.</span>
