Mitosis and Meiosis



In conclusion, mitosis and meiosis play very important roles in the multiplication of cells and the creation of new beings.


By Alec Greenbaum, Billy Grimm, Danny Taras, and Daniel Aviezer

We learned about Mitosis and Meiosis during the year, and it was a basis for other units during the year

It is important to know the processes of Mitosis and Meiosis because it explains how cells and living beings multiply eventually creating you.

There are four stages of mitosis: Prophase, Metaphase, Anaphase, and Telophase. These stages are followed by cytokinesis, which is the separating of the cell into two. Prophase is the stage where the nuclear envelope disappears and sister chromatids come together to make chromosomes. During metaphase, the chromosomes align at the metaphase plate (in the middle of the cell) independently. During anaphase, the sister chromatids separate and move toward the spindle poles equally. Finally, before cytokinesis, at telophase, the daughter cells begin to form and the nucleoli reappear.

Overview of Mitosis

Meiosis is divided into two parts: Meiosis I & Meiosis II. Meiosis I consists of the stages prophase I, metaphase I, anaphase I, and telophase I. During prophase I, homologous chromosomes, not sister chromatids, come together during synapsis(Crossing over can occur during this time)In metaphase I, the homologous chromosomes pairs meet and align at the metaphase plate and assort themselves independently. During anaphase I, the homologous pairs separate and equally move toward the spindle poles. During telophase I, the daughter cells have one chromosome from each separated homol, gous pair. After, comes meiosis II. Meiosis II is just like mitosis and occurs in both daughter cells from Meiosis I with four daughter cells as the result. This occurs only in sex cells
