Interphase+230

Interphase is a rather long phase that precedes mitosis. Interphase includes the G1 Phase, S Phase, and the G2 Phase. The G1 is a period in the cell cycle before cytokinesis and before the S Phase. For most cells, this phase is the major period of cell growth during its lifespan. During this period new organelles are being synthesized. Since organelles are being synthesized, which makes the cell require both structural proteins and enzymes, which causes a large amount of protein synthesis. At the end of this period, to ensure that the DNA is still functioning properly and the cell is functioning properly.

After G1 Phase is the S Phase.The S Phase is short for synthesis phase. When the cell enters the S Phase, DNA synthesis or replication occurs. When the S Phase first begins, each chromosome is composed of one coiled DNA double helix molecule, which is called a chromatid. Then, an enzyme splits the hydrogen bonds, which is followed by a complementary base pair being added to the DNA strand. At the end of this stage, each chromosome has two identical DNA double helix molecules. Another thing that happens during S Phase is that the centrosome is being duplicated.

The last phase of Interphase is the G2 phase. The G2 phase is the shortest of all the phases during interphase. The G2 phase is a control checkpoint and a protein kinase is used to determine if the cell can proceed to enter M phase and divide. The G2 phase prevents cells from entering mitosis with DNA damage.
