Mitosis & Meiosis

Mitosis and pupillary reflex have several(prenominal) similarities and differences. In mitosis, prison cellphones divide in four steps. First, they go through with(predicate) prophase. In prophase, the centrioles begin to shadower apart from each otherwise toward pivotal poles and the nuclear tissue layer begins to breakup. In metaphase, chromosomes gradeup at the equator of the cell, k forthwithn as the metaphase plate. In anaphase, the centromere that connects the chromatids stops and the chromatids separate from mavin another. The chromatids move toward opposite ends of the cell. In anaphase, the cell also starts to split in two, forming a segmentation furrow, the area where it pinched apart. In telophase, a nuclear membrane forms around each rising cell, resulting in two lady friend cells. The cytoplasm then begins to divide, called cytokinesis. The difference between mitosis and meiosis I is the pairing up of homological chromosomes in a place to work called synapsis in meiosis I. Because of this, this drastically changes the processes of meiosis. In prophase I of meiosis, the chromosomes go through synapsis, forming a tetrad. Everything else that happens in prophase happens. In metaphase I, the chromosomes line up at the equator of the cell, and, they encumbrance in their homologous pairs. During anaphase I of meiosis, the centromeres do not divide. Instead, the homologous pairs separate with the entire replicated chromosome woful to the opposite poles of the cell.

In telophase I, the cell undergoes the same processes as telophase in mitosis. But, sort of of 23 homologous pairs of chromosomes, there are now 23 replicated chromosomes. Meiosis II is virtually the same at mitosis, but each cell has only 23 replicated chromosomes preferably of 46. later on the cells go through telophase II, we are dedicate with four haploid cells. You leave appear spindle type formation, the differences between lay out and animal division, and crossing over. If you exigency to get a voluminous essay, order it on our website: Orderessay
