Cell Division Cycle Biology Diagrams Learn about the phases of the cell cycle, including interphase and mitosis, in this Khan Academy article. The following points highlight the four major phases of the cell cycle. The phases are: 1. G 1 (gap1) phase 2. S (synthesis) phase 3. G 2 (gap 2) phase 4. M (mitosis) phase. Cell Cycle: Phase # 1. G 1 Phase: . The G 1 phase is set in immediately after the cell division. It is characterised by a change in the chromosome from the condensed mitotic state to the more extended interphase state and
G 2 Phase. In the G 2 phase, or second gap, the cell replenishes its energy stores and synthesizes the proteins necessary for chromosome manipulation. Some cell organelles are duplicated, and the cytoskeleton is dismantled to provide resources for the mitotic spindle. There may be additional cell growth during G 2.The final preparations for the mitotic phase must be completed before the cell

Gap 2 (G2). G1 and G2 phase represents the time of growth and preparation for mitosis. The synthesis (S) phase is the phase of cell copying or cell duplication of its DNA of its entire genome. Gap 1 (G1) This is the phase in which the cell undergoes normal growth and cell function synthesizing high amounts of proteins.
Learn about the G2 phase of interphase, when the cell prepares for division by producing organelles and proteins. See diagrams, explanations, and practice questions on this topic.

The entire S-phase requires energy expenditure to proceed. G2-phase: This is the second gap phase and is somewhat similar to the G1-phase. During this period, the cells grow further in size, making more proteins and organelles. All preparations for mitosis get completed before the cells enter the mitotic phase. 2) Mitotic (M) Phase G 2 phase, Gap 2 phase, or Growth 2 phase, is the third subphase of interphase in the cell cycle directly preceding mitosis. This diagram illustrates the feedback loops underlying the G2/M transition. Cyclin-B1/CDK1 activates Plk and inactivates Wee1 and Myt1. Activated Plk activates cdc25.
