Cohesin protein. Select all that apply. It is important for maintaining homologous chromosome pairing and plays a role in recombination. It holds sister chromatids together after chromosome replication. It is required for the segregation of chromosomes during anaphase of mitosis or meiosis. It prevents sister chromatid separation until anaphase of mitosis or anaphase II or meiosis. It comprises filaments in mitotic and meiotic spindles.

Kinetochores. Select all that apply. They hold sister chromatids together after chromosome replication. They prevent sister chromatid separation until anaphase of mitosis or anaphase II or meiosis. They are required for the segregation of chromosomes during anaphase of mitosis or meiosis. They are complex structures attached to the centromeres of chromosomes that bind to spindle microtubules. They are important for maintaining homologous chromosome pairing and plays a role in recombination.
