a: Sister chromatids ~
b: pencils
What:
"Imagine you have two identical pencils held together, with their erasers at one end and their leads at the other end. Your job is to move an intact pencil to the left, and another intact pencil to the right. Would you break the pencils in half and then separate them that way? Wouldn't you end up with two erasers on one side and two leads on the other side? Sister chromatids are like those pencils. "
