Interphase comes between two successive mitosis phases. During the interphase, the cell grows by accumulating nutrients, synthesizing proteins, making new organelles and replicating its DNA.
At the end of the interphase, the cell becomes ready for the nucleus division and for making new cells. Mitosis is the second major phase of cell cycle in which nucleus divides into two nuclei that have identical genetic composition for the formation of two daughter cells. Overview and Key Difference 2. What is Interphase 3. What is Mitosis 4. Similarities Between Interphase and Mitosis 5. Interphase is the longest phase of the cell cycle.
Nucleolus and the nuclear membrane can be seen in the interphase. Interphase has three sub stages namely G1 phase , S phase and G2 phase. G1 and G2 are two gap phases. During these two phases, cell grows, cell accumulates nutrients, the cell makes organelles and cell synthesize proteins. S phase is an important phase in which DNA replication occurs.
At the end of the S phase, the cell contains two complete sets of DNA. Once the cell completes interphase, the cell enters into the mitosis phase M phase. Mitosis is the second major phase of the cell cycle. During the mitosis, cell nucleus turns into two nuclei and finally, cell devised into two cells. Mitosis extends for a short time period. There are four subphases of mitosis namely prophase, metaphase, anaphase and telophase. Mitosis ends with the cytoplasm division and becoming two daughter cells which are identical.
Chromosomes: nuclear units of genetic information; DNA molecules combined with proteins. In eukaryotes, heredity information of nucleus is distributed among several linear molecules. Chromosome Segregation: equal distribution of daughter chromosomes to each of the two daughter cells Interphase: longest phase of cell cycle External factors that influence cells: signal molecules, hormones, growth factors, death factors; bind to surface of cell and trigger a reaction.

I had to do homework on the cell divisions and this site helped me out a lot plus i am only in 7th grade and i fully understood it.
Biomedical Student. Thanks for the good cell cycle image and citation. Moreover, it is possible to divide the sequence of events of mitosis into five phases: prophase, prometaphase, metaphase, anaphase, and telophase. Mitosis takes about two hours to complete — from prophase to telophase. First, the mitotic apparatus is formed during prophase. During prometaphase, chromosomes attach to the spindle.
In metaphase, chromosomes align at the cell equator and then in anaphase, chromatids separate from each other by splitting from the centromeres.
During telophase, separated chromatids reach their respective poles. Finally, the reformation of nuclear envelopes occurs by forming daughter nuclei at two poles. Thus, this completes the nuclear division successfully. So, this is the key difference between cytokinesis and mitosis. Furthermore, mitosis has five stages: prophase, prometaphase, metaphase, anaphase, and telophase. But cytokinesis does not have such phases. The five stages of mitosis act together and separate duplicated chromosomes into two parts whereas cytokinesis divides a cell into two separate cells.
Hence, this is a significant difference between cytokinesis and mitosis. Moreover, mitosis takes place after interphase while cytokinesis takes place after mitosis. Therefore, this is also a difference between cytokinesis and mitosis. However, mitosis can occur without cytokinesis, forming single cells with multiple nuclei Ex: certain fungi and slime moulds.
Also, a further difference between cytokinesis and mitosis is the time taken for each process. That is; mitosis takes more time to complete than cytokinesis does.
