Chromosome Alignment: This refers to how chromosomes position themselves along the center of a cell during metaphase. It's like our runners positioning themselves on their lanes.
Sister Chromatids:These are identical copies of a single chromosome that will be separated during anaphase. Imagine them as twin runners who have trained together but will run separately once the race starts.
Cell Equator: Also known as metaphase plate, this is an imaginary line drawn across a dividing cell where chromosomes align during metaphase - it's just like our starting line in a race.
