Unit 5 Cell Reproduction Chp 13 Meiosis Notes
... During meiosis I, sister chromatids are attached along their lengths by protein complexes called cohesins. In mitosis, enzymes remove the cohesins to allow the sister chromatids to move to opposite poles of the cell at the end of metaphase. In meiosis, sister chromatid cohesion is released in two st ...
