1. What are the three stages of interphase?- G1 Stage, when a cell doubles its organelles and it accumulates the materials needed for DNA synthesis. S stage, is when DNA replication occurs; a copy is made of all the DNA in the cell. G2 Stage, the cell synthesizes the proteins needed for cell division, such as the protein found in microtubules.

2. How does interphase prepare a cell for cell division?- After interphase, the cell enters the cell division part of the cell cycle. Cell division has two stages: M stage and cytokinesis. Mitosis is a type of nuclear division, and Cytokinesis is dicision of the cytoplasm.
