Mitosis is the process of cell division in which a cell divides
into two daughter cells both of which will inherit same number of
chromosomes as the mother cell. For this the mother cell will go
through a round of DNA replication and has double the amount of
genetic material in it (interphase -A)
The first phase of mitosis is prophase (B) where the genetic
material condense and form visible chromosomes. Each chromosome is
attached to its duplicated copy at the centromere.
The next stage is metaphase (C). In this phase the spindle fibers
starts to form from the two poles of the cell and the chromosomes
will be arranges at the equator of the cell.
In the next stage anaphase(D) the chromosome copies are pulled apart towards the opposite poles by the spindle fibers.The next stage is telophase (E) where each of the chromosome copies are completely at the opposite poles. Nuclear envelope starts to form (karyokinesis) around the chromosomes as the spindle fibers disappear. Cytoplasm starts to divide (cytokinsesis) around the two newly formed nuclei to form two daughter cells.

During the M-phase (Mitosis), spindle fibers extend from centrioles in the poles of the cell and attach to the centromeres of each replicated chromosome. The chromosomes are aligned along the equatorial plate of the cell in the process. Once all centromeres got attached from either side to a spindle fibre, a cellular checkpoint got passed and the spindle fibers begin to contract towards the poles, pulling the two sister chromatids apart such that one sister chromatid of each of the...
