The first step is more a section with three little steps in it. It’s called Interphase. The first step in interphase is Growth 1 (or G1 for short). This is when the cell basically preps for the separation. Nothing big is happening, but it will soon. The next step is Syntheses. The DNA in the nucleus duplicates and makes copies of itself. This is also the cell preparing for Mitosis. And lastly, Growth 2 (G2) is another period where the cell gets ready for Mitosis. The DNA is duplicated and all jumbled together. Soon the separation will occurs. Also keep in mind that this is the phase that cells spend most of their time.
