WebAug 17, 2024 · As you can see in Figure 11.3. 5, the sister chromatids line up at the equator, or center, of the cell. The spindle fibers ensure that sister chromatids will separate and go to different daughter cells when the cell divides. Some spindles do not attach to the kinetochore protein of the centromeres. photobucket html editing private

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. WebSep 4, 2024 · In humans, there are over 8 million configurations in which the chromosomes can line up during metaphase I of meiosis. It is the specific process of meiosis, resulting in four unique haploid cells, that results in these many combinations. WebDuring metaphase I, the homologous chromosomes are arranged in the center of the cell facing opposite poles. Random orientation of the homologous pairs occurs at the equator. This is important in determining the genes carried by a gamete. Each gamete will only receive one of the two homologous chromosomes. Homologous chromosomes are not … how does the greenhouse work
