A vibrant cartoon with colours and smooth animation. Create a 20-second cute 3D cartoon animation explaining mitosis. The main character is a cute round cell with big expressive eyes, a small smiling mouth, and funny facial expressions. Inside the cell are cute little chromosome characters with eyes. Show the cell moving and dividing: the chromosomes first appear inside the cell, then line up in the middle, then separate and move to opposite sides. Finally, the cell splits into two identical cute cells, both smiling and waving. Make it fast, fun, colorful, and clearly AI-animated. Use smooth movement and expressive characters. No slides .
