While dividing, extra chromosomes could have been present that weren't necessary. Having one or more extra sex chromosomes leads to Klinefelter's Syndrome. Having an extra chromosome 21, leads to Down's Syndrome. Another common problem is to have an extra chromosome 13 which causes Trisomy 13 Syndrome.
I'm finally finished dividing! My cytoplasm is divided as well. I am turned into a cleavage furrow before I am made into two identical daughter cells!
In this phase, my chromosomes unwind, my nuclear envelope reforms, and my nucleus finishes dividing. My journey is nearing the end!
I am currently in the shortest phase of cell division! In Anaphase, my spindle fibers shorten to pull sister chromatids apart. Other microtubles of my spindle increase in length, also increasing the size of me!
My chromosomes line up at my metaphase plate, which is located across the middle of me. Then, spindle fibers attach to centromere.
During prophase, my DNA condenses to form chromosomes. The nuclear envelope inside of me disappears. Just when I think this phase is over, my centrioles move toward opposite poles!
I am in the first phase of cell division and am feeling a little anxious because I know I will spend most of my life here. I will go through three stages in this phase; G1 (growth 1), S (synthesis), and G2 (growth 2). In G1, I will carry out my normal functions, continue to grow, and engage in metabolic activity. In S, my DNA copies. At the end of this stage, all of my chromosomes will have two chromatids. In G2, I will begin to prepare for cell division!
I am a human skin cell and I am going to be dividing very soon! Be sure to keep up with my blog as I write about my journey going through cell division.
