“Imagine Spider-Man is standing in a set position and needs to get something. He throws a web at the thing he wants, and then drags it to him. Now imagine that a very tiny Spider-Man is standing at one end of a cell. He throws a web at the chromosome he wants, the web attaches, and he pulls the chromosome to his end of the cell. A tiny Spider-Man clone does the same thing at the opposite end of the cell for the other chromosome in the matching pair.”
