- What's S Phase? The second part of interphase is the synthesis (S) phase. It happens after G1_11 phase. The name is fitting because this is when DNA synthesis takes place. Duri…

- What Is the S Phase of Interphase? S Phase is a part of interphase of the cell cycle. It is a crucial step of cell division. During this step, the cell replicates its DNA so tha…
