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.
The first phase of mitosis is prophase. During this phase the nucleus disappears. Once the nucleus has disappeared, the centrioles move from the center of the cell to different ends of it. Fibers cross and form the mitotic spindle. Once the fibers have extended and centrioles have separated, prometaphase begins.
