What is origin firing and when does it occur during the S phase?

What occurs during the S phase of the cell cycle? 1) the genetic material is copied, 2) chromosomes replicate and become double stranded chromatids.

In the first phase (G1) the cell grows and becomes larger. When it has reached a certain size it enters the next phase (S), in which DNA-synthesis takes place. ... in the mother cell or a single nucleus arrested in the isthmus between the mother cell and the daughter bud. Exposure of unbudded stationary-phase cells to ... The S phase of the cell cycle occurs before the interphase and is involved in DNA synthesis or replication. S phase. S stands for Synthesis phase.
