Reproduction PowerPoint Presentation Biology Diagrams G 2 phase, Gap 2 phase, or Growth 2 phase, is the third subphase of interphase in the cell cycle directly preceding mitosis.It follows the successful completion of S phase, during which the cell's DNA is replicated.G 2 phase ends with the onset of prophase, the first phase of mitosis in which the cell's chromatin condenses into chromosomes.. G 2 phase is a period of rapid cell growth and
The G 2 /M phase is necessarily a transient state in which the morphology of the plasma membrane becomes analogous to a bicontinuous cubic phase (Fig. 7) [31,32,77,78]. This type of lipid assembly has been reviewed in some detail recently [79,80] , including its relevance to biological systems [30,81,82] . Cell growth is central to the cell cycle, and this is the primary purpose of interphase. At the end of this phase, there is double the amount of DNA, centrioles have replicated, and the cell is big enough for cell division. Interphase consists of the first growth (G1 phase), Synthesis (S phase), and the second growth (G2 phase) phases (figure 1

The G2 Phase: Preparing for Cell Division Biology Diagrams
The G2 phase, or Gap 2 phase, represents a crucial stage in the cell cycle where the cell undergoes final preparations for mitosis.Following the S phase, during which DNA replication occurs, the cell enters G2 to ensure that all necessary components are in place for successful cell division.ThiS phase is marked by various processes, including further growth, organelle replication, and the G2 is the shortest phase of interphase. It is when organelles and proteins necessary for cell division are produced. The cell requires a bunch of proteins and other stuff to separate the chromosomes and divide the cell in half. All of these materials are produced during G2. The cell also checks for DNA damage in this phase.
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
Cell Cycle Phases and Checkpoints Biology Diagrams
The cell cycle consists of a timed sequence of events that occur during interphase and mitosis (M). Interphase is made up of the G 1 (G = gap) phase, the S (synthesis) phase, and the G 2 phase (Fig. 15-2).Both G phases contain checkpoints that govern whether the cell moves into DNA replication (G 1 checkpoint) or into mitosis (G 2 checkpoint).. The G 1 and G 2 phases involve the synthesis of Importantly, this phase ensures that everything is in place for DNA synthesis to occur in the next phase. S Phase (Synthesis): During this phase, the cell's DNA replicates. At the end of the S phase, each chromosome consists of two chromatids attached at the centromere. G2 Phase (Gap 2): Here, the cell continues growing and prepares for
