chromosomes attach to spindle fibers
The chromosome pairs are lined up in the center of the cell, parts of the cytoskeleton have formed the mitotic spindle and are preparing to pull the pairs apart.
In Mitosis and Meiosis, this event is called Metaphase.
The chromosomes attach to a spindle fiber across the equator of the cell.
The event that immediately precedes anaphase is metaphase, where the chromosomes align at the cell's equator, forming a metaphase plate. This alignment ensures that when anaphase commences, the sister chromatids can be pulled towards opposite poles of the cell by the spindle fibers.
During metaphase, the chromosomes align at the metaphase plate in the center of the cell. The spindle fibers attach to the centromeres of the sister chromatids, preparing to separate them during anaphase. Metaphase is a critical step in mitosis in ensuring accurate chromosome segregation.
Interphase ,Prophase,Metaphase,Anaphase && Telophase } Also cytokinesis
Meiosis consist of two main stages: meiosis I and meiosis II. Meiosis I includes prophase I, metaphase I, anaphase I, and telophase I with the key event being homologous chromosomes separating. Meiosis II involves prophase II, metaphase II, anaphase II, and telophase II, where sister chromatids separate, resulting in the formation of haploid cells.
the four phases of mitosis are prophase, metaphase, anaphase, and telophase
Main Event was created in 1997.
his main event was to find a spice
No, homologous chromosomes do not pair up during metaphase 2 as they do in metaphase 1. In metaphase 2, individual chromosomes line up along the metaphase plate.
Metaphase 1 The chromosomes line up on the equatorial (metaphase) plate. Metaphase 2 Kinetochores of the paired chromatids.
