WebbProphase During prophase, the chromosomes, which had been thin and threadlike in interphase, begin to condense, or thicken. The nuclear membrane surrounding the cell nucleus disintegrates, the nucleolus disappears, and the centrosomes move toward opposite poles of the cell.

In a human being, the haploid cells made in meiosis are sperm and eggs. At the point when a sperm and an egg participate in fertilization, the two haploid arrangements of chromosomes create a complete diploid set: another genome. イオン大井町

"WebbCytokinesis. Cytokinesis is the process in which the cell actually divides into two. With the two nuclei already at opposite poles of the cell, the cell cytoplasm separates, and the cell pinches in the middle, ultimately leading to cleavage. In most cells, the mitotic spindle determines the site where the cell will begin to invaginate and split. " - Prophase short summary
