Nettet13. apr. 2024 · During microgenesis, both the movement of homologous or sister chromosomes and postmeiotic cytokinesis are closely related to dynamic changes in the organization of microtubules [46,47]. In diploid Populus species, the misorientation of spindle microtubules and the failure of postmeiotic cytokinesis have been attributed to … NettetAnaphase The sister chromatids separate into individual chromosomes and are moved apart. Interphase The cell grows and replicates its DNA and centrioles. Prophase The chromatic condenses into chromosomes. The centrioles separate, and a spindle begins to form. The nuclear envelope breaks down. Metaphase Nettet20. nov. 2024 · Meiosis and mitosis both have a prophase, metaphase, anaphase, telophase and cytokinesis. In meiosis, prophase, metaphase, anaphase and telophase occur twice. The first round of division is special, but the second round is more like mitosis.

The mitotic spindles are …

Nettet9. apr. 2024 · In anaphase I, the microtubules pull the linked chromosomes apart. The sister chromatids remain tightly bound together at the centromere. The chiasmata are broken in anaphase I as the microtubules attached to the fused kinetochores pull the homologous chromosomes apart (Figure 11.1. 4 ).
