So during this phase of anaphase, the spindle fibers pull the identical chromosome pairs apart by breaking our centromeres. And this is shown in this diagram. And when we break the centromeres, each one of these chromatids has its own unique centromere region. Now, the identical chromosomes in any pair, also known as sister chromatids, begin to move to opposite ends, as shown in the diagram. And this separation of chromosomes is known as this junction. Now let's move on to telephase.
