Chromatin Condensation: This process involves tightly packing DNA material into distinct shapes that we recognize as chromosomes - much like neatly arranging all your chess pieces before you start playing.
Spindle Fibers: These are protein structures that move chromosomes during cell division. They're like the hands that physically move your chess pieces across the board.
Centromere: This is a region of DNA where two identical sister chromatids come in contact and where spindle fibers attach during cell division - it's like the base of each chess piece, holding it together.
