A divide is the highest ridge of terrain separating river basins. Divides can be relatively small and cover just a few dozen miles, or they can stretch thousands of miles. On either side of a divide, water drains into separate basins. Continue Reading.
Concept 2: Mitosis and the Cell Division Cycle. Cells that are growing and dividing go through a repeating series of events called the cell division cycle (or cell cycle). During the first phase (G1), the cell grows and prepares for DNA replication, which occurs in the subsequent S phase. Further growth takes place in the G2 phase, and finally mitosis occurs in the M phase. G1, S, and G2 are collectively called interphase.
When does replication occur in the replication of DNA? In Mitosis - the events that prepare the Eukaryotic Cell for division and the division process itself constitute a complex cell cycle. Interphase is the 1st phase of the cycle â¦ and is made-up of 3 phases (G1, S, & G2).
