The Microscopic Identification of the Phases of Mitosis Using Onion Root Tip Cells
Lauren Harvey and Jason Levigne
Background:
Mitosis is part one of the Mitotic Phase. The overall outcome the Mitotic Phase is taking one diploid cell (2n) and splitting it into two diploid (2n) cells. The Mitotic Phase includes two parts: Mitosis and Cytokinesis. The main goal of the Mitotic Phase is to achieve two things, both division of the genetic nuclear material, otherwise known as DNA, and the division of the cytoplasm. Once these requirements are all met, the Mitotic Phase will have successfully completed in making one diploid cell into two diploid cells. The first step of the Mitotic Phase is Mitosis, Mitosis too has parts that make it up. The process of Mitosis is composed of four phases: Prophase, Metaphase, Anaphase, and Telophase. Prophase, the first phase of Mitosis, follows Interphase. Interphase is the time between divisions, although it is not considered to be a part of Mitosis, it is still helpful to the achieving the main goal of the Mitotic Phase. Interphase consists of four phases: G1 Phase, S Phase, G2 Phase, and M phase. In these phase are checkpoints which check to determine whether or not the cell is ready enough to undergo the process of Mitosis. Once cells are successfully checked and prepped in Interphase, the cell continues into the first part of the Mitosis. In Prophase, the chromosomes will coil up and the nucleus and nucleolus will disappear. The next phase of…
