The video discusses metaphase, a crucial stage in both mitosis and meiosis. It explains the alignment of chromosomes at the metaphase plate, the role of spindle checkpoints, and the differences between metaphase in mitosis and meiosis. The video also highlights the applications of metaphase in detecting genetic abnormalities through karyotyping.
