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.
During the S phase the cell replicates the chromosomes by taking one chromatid and effectively doubling it (these are later ripped apart during Anaphase in Mitosis). So during the S phase of the Interphase cycle, chromosomes are replicated into two sister chromatids. Normally after this phase there is a check off to make sure nothing went wrong with the replication however should there be any mutations that will create some new DNA form this is where it would be made.
