Have you ever asked yourself how is it that you grow? Have you ever wondered what happens inside of you?
A process called the “Cell Cycle” is what occurs inside of you. One of the Cell Cycle’s phases is the “Mitotic Phase”, or “M Phase”, and also the “DNA Replication” occurs. DNA Replication is the process of producing two identical replicas, or as they are called daughter cells, from one original DNA molecule. Daughter cells have an identical set of chromosomes, and chromosomes make copies called chromatids.
Back to the M Phase, or Mitosis. In Mitosis, four phases occur. The first one is called Prophase. In this process, chromatids become dense, protein structures form and start to move into place, and the nuclear envelope begins to dissolve. Then comes Metaphase, here, chromatids line up at the middle of the cell, or if you want to see the cell as if it were a globe it would be the equator of the cell. Also, the spindle is formed. Next, Anaphase occurs, where chromatids separate, and free chromosomes move to the opposite ends of the cell. Finally comes the Telophase, in which two new nuclei is formed, the “clean up” begins, and the cell begins to divide. After all of this is finished, Cytokinesis occurs, which is cell movement.
We can conclude that when you grow what basically happens is that your cells multiply or reproduce making you bigger.
