This essay provides a summary of two videos explaining the processes of mitosis and meiosis. The first video illustrates mitosis using colored beads to represent chromosomes, highlighting the duplication process and the formation of sister chromatids. The essay describes the stages of mitosis, including prophase, metaphase, and anaphase. The second video focuses on meiosis, also starting with interphase and the duplication of chromosomes. It details the two divisions in meiosis, including prophase I and II, metaphase I and II, anaphase I and II, and telophase I and II. The essay also discusses the crossing over of chromosomes during prophase I, and the separation of chromosomes and chromatids. The essay concludes with a discussion on the formation of four new cells at the end of meiosis II.
