Mitosis & Meiosis

Mitosis and meiosis have several similarities and differences. In mitosis, cells divide in four steps. First, they go through prophase. In prophase, the centrioles begin to after part apart from each other toward pivotal poles and the nuclear tissue layer begins to breakup. In metaphase, chromosomes melodic lineup at the equator of the cell, k nowadaysn as the metaphase plate. In anaphase, the centromere that connects the chromatids splits and the chromatids separate from one another. The chromatids move toward opposite ends of the cell. In anaphase, the cell also starts to split in two, forming a division furrow, the area where it pinched apart. In telophase, a nuclear membrane forms around each new cell, resulting in two female child cells. The cytoplasm then begins to divide, called cytokinesis. The difference between mitosis and meiosis I is the pairing up of homologous chromosomes in a flummox to work called synapsis in meiosis I. Because of this, this dr astically 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 stay in their homologous pairs. During anaphase I of meiosis, the centromeres do not divide. Instead, the homologous pairs separate with the entire replicated chromosome miserable to the opposite poles of the cell. is a professional essay writing service at which you can buy essays on any topics and disciplines!

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 2 3 replicated chromosomes. Meiosis II is vir! tually the same at mitosis, but each cell has only 23 replicated chromosomes kinda of 46. later on the cells go through telophase II, we are go forth with four haploid cells. You leave out spindle grapheme formation, the differences between lay out and animal division, and crossing over. If you deficiency to get a copious essay, order it on our website:
