MEDICAL ANIMATION TRANSCRIPT: Mitosis is a type of cell division with many vital functions, including embryonic development, promoting tissue growth after birth, and replacing damaged or dying cells in the body. In mitosis, there is one division, and the resulting two daughter cells contain the same number of chromosomes as the parental cell. These cells are called diploid cells because they contain 23 pairs of chromosomes, with each pair containing one maternal and one paternal chromosome. After DNA replication, mitosis begins with prophase, during which chromatin condenses into chromosomes, each consisting of two identical sister chromatids. The nuclear envelope dissolves, and spindle fibers begin to grow from the cell's centrioles. During metaphase, the spindle fibers pull the chromosomes into alignment in the center of the cell. In anaphase, each chromosome, consisting of two genetically identical chromatids, splits in two. Each chromatid, now considered a single-stranded daughte...
