What Is Mitosis?
Mitosis is the division of cells. Two daughter cells emerge from a mother cell. The two daughter cells have the same genetic information or nuclei of the parent nucleus.
Mitosis is the division of cells. Two daughter cells emerge from a mother cell. The two daughter cells have the same genetic information or nuclei of the parent nucleus. All kinds of asexual reproduction occur due to this process. Mitosis is also responsible for growth regeneration and cell replacement in multi-cellular organisms.
The first stage of mitosis is interphase. The stage is basically a resting stage, but some small activities do occur. The DNA begins to replicate itself and forms mRNA, tRNA and r RNA.
Prophase is where the real interesting events start to occur. Chromatids shorten and thicken during this stage of mitosis. The nucleoli disappear and the nuclear membranes break down and go away during the stage. Animal cells have the division of the centrioles and centrosome.
Metaphase is the middle of the process in the 5-step procedure. This is where the real division begins. The chromosomes move to the middle or equator of the spindle. The paired chromosomes attach to the spindle at the centromere.
Anaphase can be understood as the separation stage. The chromosomes lined up in metaphase and now in anaphase they say their last goodbyes. The sister chromatids split into a single stranded chromatids. The Chromosomes begin to migrate to opposite sides of the cell.
Finally, in telophase, the parent cell has become two. The chromosomes uncoil and new nuclei in the two daughter cells have begun to emerge. In plant cells, a cell plate appears at the equator that divides the parent cell into daughter cells. In animal cells, an invagination of the plasma membrane results in the division of the parent cell.
Mitosis is life. Two forms from one. Without mitosis, the world could not exist and genetic information could not be spread.
