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.
Mitosis - nuclear division. Before a cell divides, its nucleus must divide, in order to pass on this information to both daughter cells. In higher plants and animals a process known as ensures that chromosomes, after dividing, are distributed evenly between the two cells. In other words, division comes before division. As a result of mitosis, each dividing cell produces two cells, each of which contains identical sets of chromosomes.
