The cell pinches together in the middle and separates into two daughter cells, each with a complete set of chromosomes. Thus, each daughter cell has a complete copy of all the genes in the original cell. ... Demonstrate how the sister chromatids of each … WebIn metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles. In telophase, chromosomes arrive at opposite poles, and nuclear envelope material surrounds each set of chromosomes.
