Interphase. 1  G1 phase: The period prior to the synthesis of DNA. 2  S phase: The period during which DNA is synthesized. 3  G2 phase: The period after DNA synthesis has occurred but prior to the start of prophase.  In the latter part of interphase, the cell still has nucleoli present.â.
The interphase is divided into three subdivisions: G1 (gap one), S (synthesis) and G2 (gap two). During G1, the cell manufactures a range of proteins that are required for DNA replication. The chromosomes are then replicated during the S stage. Each replicated chromosome consists of two sister chromatids, thus effectively doubling the cell's DNA.
