WitrynaExpressing two meiotic proteins, Spo13 and Rec8, prevents sister chromatids from separating at mitotic anaphase. Because Spo13 and Rec8 are both required for normal chromosome behavior in meiosis I, we suggest that Spo13 protects a subset of meiotic cohesin during anaphase of meiosis I and metaphase of meiosis II.
