Before the cohesins can be broken apart, the mitotic spindle checkpoint must be met, meaning all chromosomes are attached to microtubules from both sides and are aligned on the metaphase plate. the pirates bays

WebApr 23, 2024 · At the very start of the metaphase stage, the pairs of condensed chromosomes line up along the equator of the elongated cell. Because they are condensed, they can move more easily without becoming tangled. Some biologists actually separate metaphase into two phases: prometaphase, and true metaphase. Webchromosomes line up at the metaphase plate each sister chromatid is attached to a spindle fiber originating from opposite poles Anaphase During anaphase, proteins that bind the sister chromatids together break down. The connected sister chromatids, now called chromosomes, pull toward opposite poles and cause the chromosomes to split. WebApr 9, 2024 · During metaphase I, the homologous chromosomes are arranged in the center of the cell with the kinetochores facing opposite poles. The homologous pairs orient themselves randomly at the equator. For example, if the two homologous members of chromosome 1 are labeled a and b, then the chromosomes could line up a-b, or b-a. side effects of high zinc levels
