Hi, my name is T'Challa and I´m the strongest tiger in the savannah.
Oh sh*t! I got a wound fighting for a woman. I will undergo Mitosis.
Let's get to work gentleman! Start with the duplication of DNA and also get bigger and bigger!
My chromatids are condensing. My nucleus is disappearing. The biotic spindle is forming. Everything going as planned!
Chromosomes aligning in the Metaphase Plate!

This comic will talk about and explain Mitosis and how this wonderful process is very important for all living things.
Agggh! My sister chromatids are being pulled apart!
Mitosis is a type of cell division, that only happens in somatic or body cells, in which one cell divides to produce two new cells that are genetically identical to itself. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
Oh, who is that newcomer? He looks just like me. But wait, he is attached to me!
Before a dividing cell enters mitosis, it undergoes a period of growth called interphase. About 90 percent of a cell's time in the normal cell cycle may be spent in interphase. The interphase can be divided into different steps: G1 phase, the period before to the synthesis of DNA. S phase, the period during which DNA is synthesized. G2 phase, The period after DNA synthesis has occurred but before to the start of prophase.
Finally we're separated from each other, but who are you?
In prophase, the chromatin condenses into chromosomes. The nuclear envelope breaks down and spindles form at opposite poles of the cell. Prophase is the first true step of the mitotic process.
Thanks Captain Somatic! My wound is now cured, now I'll go again for that woman. She has to be mine!
In metaphase, the spindle reaches maturity and the chromosomes align at the metaphase plate (a place that is equally distant from the two spindle poles). Also during this phase the following changes occur: the nuclear membrane disappears completely, chromosomes move randomly until they attach at their kinetochores to fibers from both sides of their centromeres.
In anaphase, the paired sister chromatids separate and begin moving to opposite ends of the cell. Spindle fibers not connected to chromatids lengthen and elongate the cell. At the end of anaphase, each pole contains a complete compilation of chromosomes. Also in preparation for telophase, the two cell poles also move further apart during the course of anaphase. At the end of anaphase, each pole contains a complete compilation of chromosomes.
In telophase, the cell is nearly done dividing, and it starts to re-establish its normal structures as cytokinesis takes place. The following events occur: the mitotic spindle is broken down into its building blocks, two new nuclei form, one for each set of chromosomes, nuclear membranes and nucleoli reappear and the chromosomes begin to decondense.
Cytokinesis is the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase. At the end of cytokinesis, two genetically identical daughter cells are produced. These are diploid cells, with each cell containing a full complement of chromosomes.
As we saw, mitosis is the process that happens for the creation of somatic or body cells, this process is used to repair damages as wounds and grow. We saw that mitosis follows some steps in order to create a new cell, which are Interphase this is the longest phase, Prophase, Metaphase, Anaphase and Telophase (long for PMAT) and finally cytokinesis to separate the new cell
