Gravel Road Construction. Although gravel road construction can be done anytime on any surface, a smooth, long-lasting roadway requires the right process. Like any other building project, a gravel road starts with the foundation. The other three stages are sub-grade material, sub-base material and gravel surface.
Actually, organelle replication, occurs during the G2 stage of the cell cycle. During this stage, organelles are replicated and proteins are synthesized. The G2 phase follows DNA replication which occurs during the S-phase. The actual cell cycle begins with the resting phase called G0, followed by the G1 phase, the S and G2 phases which are known as interphase. The M or mitosis phase is when the cell divides into two daughter cells. During G0,... Actually, organelle replication, occurs during the G2 stage of the cell cycle. During this stage, organelles are replicated and proteins are synthesized. The G2 phase follows DNA replication which occurs during the  S-phase.
This structure divides into many pieces contained in vesicles which are then separated into the two daughter cells. This is a common way for organelles which only have one copy in the cell to segregate into the two daughter cells. These organelles do not appear to replicate before cell division the way DNA does. During the gap phases (G1 and G2) the cell increases the amount of protein and organelles it contains in preparation for cytokinesis. How exactly the cell partitions its organelles during division is not well understood.
