Interphase is the phase of the cell cycle in which a typical cell spends most of its life. In the cell cycle, interphase is preceded by telophase and cytokinesis of the M phase.
In cells with a nucleus, as in eukaryotes, the cell cycle is also divided into two main stages: interphase and the mitotic (M) phase (including mitosis and cytokinesis).

Mitosis

mitoticmitosesmitotic division
During interphase, the cell copies its DNA in preparation for mitosis. A common misconception is that interphase is the first stage of mitosis, but since mitosis is the division of the nucleus, prophase is actually the first stage. In interphase, the cell gets itself ready for mitosis or meiosis.
In general, mitosis (division of the nucleus) is preceded by the S stage of interphase (during which the DNA is replicated) and is often accompanied or followed by cytokinesis, which divides the cytoplasm, organelles and cell membrane into two new cells containing roughly equal shares of these cellular components.

Prophase

chromatin condensation
A common misconception is that interphase is the first stage of mitosis, but since mitosis is the division of the nucleus, prophase is actually the first stage.
Beginning after interphase, DNA has already been replicated when the cell enters prophase.

The actual function of the veil is not clear, although it is excluded from the nucleolus and is present during interphase.

Meiosis

Cytokinesis

cytokineticactin-myosin contractile ringcytokines
In the cell cycle, interphase is preceded by telophase and cytokinesis of the M phase.
After the completion of the telophase and cytokinesis, each daughter cell enters the interphase of the cell cycle.

G2 phase

G2G 2 G 2 phase
The first process, non-homologous end joining (NHEJ), can join the two broken ends of DNA in the G1, S and G2 phases of interphase.
G 2 phase, or Gap 2 phase, is the third subphase of interphase in the cell cycle directly preceding mitosis.

G1 phase

G1G 1 phaseG 1
The first process, non-homologous end joining (NHEJ), can join the two broken ends of DNA in the G1, S and G2 phases of interphase.
In this part of interphase, the cell synthesizes mRNA and proteins in preparation for subsequent steps leading to mitosis.

DNA replication

replicationreplication forklagging strand
However HRR is only active during the S and G2 phases of interphase when DNA replication is either partially accomplished or after it is completed, since HRR requires two adjacent homologous chromosomes.
DNA replication occurs during the S-stage of interphase.

Telophase

nuclear division
In the cell cycle, interphase is preceded by telophase and cytokinesis of the M phase.
As chromosomes reach the cell poles, a nuclear envelope is re-assembled around each set of chromatids, the nucleoli reappear, and chromosomes begin to decondense back into the expanded chromatin that is present during interphase.

Cell division

divisiondaughter cellcellular division
In the cell cycle, interphase is preceded by telophase and cytokinesis of the M phase. After the successful completion of mitosis and cytokinesis, both resulting daughter cells re-enter G 1 of interphase.
Interphase is the process a cell must go through before mitosis, meiosis, and cytokinesis.

Interphase is the phase of the cell cycle in which a typical cell spends most of its life.

Metabolism

Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions.

Somatic cell

Somatic cells, or normal diploid cells of the body, go through mitosis in order to reproduce themselves through cell division, whereas diploid germ cells (i.e., primary spermatocytes and primary oocytes) go through meiosis in order to create haploid gametes (i.e., sperm and ova) for the purpose of sexual reproduction.Chromosomes are copied

There are three stages of cellular interphase, with each phase ending when a cellular checkpoint checks the accuracy of the stage's completion before proceeding to the next.
