Meeting this challenging task requires an understanding of the meaning of empathy, the use of diverse educational techniques, and incorporation of students' personal experiences. Acknowledging the role of empathy is easy, but teaching empathy is difficult because empathy is an elusive idea.
The sister chromatids are connected to each other at a point called the centromere. During mitosis, the nuclear envelope dissolves, and sister chromatids separate at the centromere, becoming two individual daughter chromosomes, each now with only one chromatid.
During anaphase, the spindle fibers pull the identical sister chromatids to opposite sides (poles) of the parent cell. The fourth and final step of mitosis is telophase. During telophase, two nuclear envelopes reform around the separated DNA and the DNA de-condenses so that chromosomes are no longer visible. One can also see that the plasma membrane begins to constrict between the newly formed nuclei.
