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. So in telephase, these spindles basically move our cystochromatids to opposite ends, so that once we are in telephase, each end of the cell now contains the identical set of chromosomes. So we have four on the left end and four on the right end. Now, what also begins to happen is the nuclear membrane begins to reform, but it begins to reform on both sides.
