ryan moon Mitosis is simply the process of creating cells
through cell division. What is it? Through certain steps, the parent's genetic material is passed down to the offspring. How does it happen? It goes through a stage called How does it split? Importance of Mitosis 'Interphase' "Stage where the cell
grows until it is big enough to replicate" Interphase Process Interphase is the growing of the cell before going through mitosis.

There are 3 stages in Interphase, and they are G1, S, and G2.

In the G1 stage, the cell increase in mass in preparation for division of cell. G1 stands for ' the first gap phase'.

In the S stage, the DNA of cell is synthesized here. That is why S stands for synthesis.

In the final G2 stage, the cell synthesizes proteins and continues to grow greater in size. G2 stands for the second gap phase.

The G0 process is when the cell rests, because it is unnecessary to regenerate. Mitosis Process Growth Vegetative Reproduction Cell Replacement Mitosis helps cells to
increase in number and this occurs to
multicellular organisms Some plants are able to produce offspring that are genetically similar with themselves. These are called “clones” and they are formed by mitosis. Damaged tissues can be repaired by mitosis. Some organisms can regenerate their body parts, and these can be achieved by mitosis. Interphase Stage where cells
grow before
replicating Prophase The chromatin form into discrete chromosomes Prometaphase It is part of prophase, when
nuclear membrane dissolved
and proteins are attached to
kinetochores. Metaphase Chromosomes are aligned at the
metaphase plate (a plate that is
equally distant from the
two spindle poles.). Anaphase The paired chromosomes
move to opposite
ends of cell. At the end of anaphase, each pole contains a complete collection of chromosomes Telophase Chromosomes are cordoned
off in distinct new nuclei in
the emerging offspring cell Cytokinesis Cytokinesis is the division of the cytoplasm and the cell membrane after the division of the nucleus, resulting into two cells, each having its own nucleus and cytoplasm surrounded by its own plasma membrane.

In short, it is the separation process of a cell resulting in two cells. How long does this cycle take? Depending on the human's needs, it goes through one cycle of about 30 minutes.
