In what stage are sister chromatids formed
WebCell Division Stages - Anaphase. In the anaphase, sister chromatids (meiosis II and mitosis) or homologous chromosomes (meiosis I) are pulled to opposite ends of the mother cell by the spindle fibres. Cell Division Stages - Telophase. During this stage, the chromatids or chromosomes reach opposite poles of the cell. Web18 dec. 2012 · We previously reported that CLB3 expression prior to meiosis I induces a change in the pattern of chromosome segregation such that sister chromatids, instead of homologous chromosomes, segregate during the first nuclear division (Carlile and Amon, 2008).To determine how Clb-CDKs impact meiotic chromosome segregation and …
