Chromosomes, Mitosis, and the Cell Cycle: How New Cells are Made for Growth and Repair

The video explains the necessity of new cells for growth and repair, using examples like a growing giraffe and an injured finger. It introduces the cell cycle, where genetic material is doubled and divided into two identical cells. The video covers chromosomes, DNA, and genes, explaining their roles in cell division. It details the three stages of the cell cycle: cell growth and DNA replication, mitosis, and cell division.
