Interphase proceeds in three stages, G1, S, and G2.
G1 Phase
After mitosis is complete the new daughter cell begins to accelerate its biochemical processes which were slowed down by mitosis. The length of the G1 phase creates the difference between fast dividing cells and slowly dividing cells. The G1 phase can be slowed by reducing the nutrients available in a system - thus the cell will take longer to build up the resources necessary for cell division. If there is a severe depletion in nutrients the cells can virtually stop growing. It is interesting to note that cells that aren't growing are always stopped in the G1 phase, being mitotically arrested. This suggests that once the cell enters the S phase, it is committed to cell division, regardless of the external cell conditions.
S Phase
The S phase begins with the replication of the cellular DNA. This is described in further detail in DNA replication. When the cellular DNA has been duplicated, leaving the cell with twice as many chromosomes (each chromosome is made up of two identical chromatids), the cell moves onto the G2 phase.
G2 Phase
During this phase proteins, such as kinase (which catalyzes protein phosphorylation), which are necessary for cell division are synthesized at this time. The chromosome begins to condense and the proteins necessary for construction of the mitotic spindle also are synthesized. When the chromosomes become visible the cell enters the first stage of mitosis, prophase.

What are the three stages of interphase called?
The three phases of interphase are : G1 (Gap 1) where the cell may grow up to double its volume by protein synthesis. The S, or synthesis phase allows for the duplication of DNA G2 (Gap 2) where the cell continues to grow in preparation of duplication. After each stage, a checkpoint allows for advancement to the next stage of interphase if the cell is ready.
Which three phases make up interphase?
The three phases that make up interphase are G1, S, and G2.
What is the longest part of mitosis?
There are five stages of mitosis, beginning with interphase and ending with telophase. Interphase is the longest phase, during which the centrioles and DNA replicate and preparations are made for mitosis to occur.
Which stages are associated with Interphase?
Interphase is the portion of a cells mitosis. It is when the cell is resting, and building up the important supplies for the next split. It is often the longest stage, and is followed in order by: Prophase, Metaphase, Anaphase, Telophase, & Cytokinasis
Summarize what happens during interphase?
Interphase is the stage in which the cell grows, matures, and replicates its DNA. It is divided into three phases - G1, S, and G2. During interphase the cell prepares itself for cell division.
What are three stages of the cell cycle of a eukaryotic?
Interphase, mitosis, and cytokinesis.
What are the three stages of the cell cycle in a eurkaryotic cell?
Interphase,Mitosis,Cytokinesis
What are the three stages of the cell cycle?
The three stages of the cell cycle are interphase mitosis and cytokinesis. Interphase is when the cell grows and get all the nutrients that it need for mitosis, and replicates the DNA. Mitosis is when the cell divides into two daughter cells. Finally cytokinesis when the cells are completely separated.
Between anaphase interphase metaphase and prophase which does not belong?
Interphase does not belong because it is not a phase of mitosis. The other three - anaphase, metaphase, and prophase - are stages of mitosis where the cell undergoes specific changes in preparation for division. Interphase is the phase where the cell carries out normal functions and prepares for division.
What are the three stages cell cycle?
The three stages of the cell cycle are interphase mitosis and cytokinesis. Interphase is when the cell grows and get all the nutrients that it need for mitosis, and replicates the DNA. Mitosis is when the cell divides into two daughter cells. Finally cytokinesis when the cells are completely separated.
What are three stages of cell cycle?
The three stages of the cell cycle are interphase mitosis and cytokinesis. Interphase is when the cell grows and get all the nutrients that it need for mitosis, and replicates the DNA. Mitosis is when the cell divides into two daughter cells. Finally cytokinesis when the cells are completely separated.
What phase is about 90 percent of the cell cycle?
The phase where about 90% of the cell cycle occurs is interphase. Interphase consists of three stages: G1 phase, S phase (synthesis), and G2 phase. During interphase, the cell grows, performs its normal functions, and replicates its DNA in preparation for cell division.
What are the stages of cell cycle?
The cell cycle consists of two main stages: interphase and mitotic phase. Interphase includes three sub-stages: G1 (cell growth), S (DNA replication), and G2 (preparation for cell division). The mitotic phase consists of mitosis (nuclear division) and cytokinesis (division of the cytoplasm).
What does iPMAT mean?
Interphase, Prophase, Metaphase, Anaphase, and Telophase (stages for mitosis) :D Interphase, Prophase, Metaphase, Anaphase, and Telophase (stages for mitosis) :D
What does interphase make copies of?
There are three stages in interphase G1, S, and G2. G1 the cell grows. S the DNA is copied and sister chromatids appear. G2 the cells grows and specializes DNA.
Which is a part of interphase A.Prophase B.G1 phase C.Telophase D.Cytokinesis?
B. G1 phase. Interphase consists of three main stages: G1 phase, S phase (synthesis), and G2 phase. Prophase, telophase, and cytokinesis are stages of mitosis.
What is the outcome of interphase?
Interphase is where the cell is when it is preparing for cell division. Therefore the purpose of interphase is to prepare the cell for division. During interphase, the cell goes through three stages; the G1, S Phase and G2. This is the longest part of the cycle.
