You are watching: Part of eukaryotic cell division during which the cell nucleus divides

Divide and Split

Can friend guess what this vivid image represents? It reflects a eukaryotic cell during the procedure of cabinet division. In particular, the photo shows the nucleus of the cabinet dividing. In eukaryotic cells, the cell core divides prior to the cell itself splits in two; and before the cell nucleus divides, the cell’s DNA is replicated, or copied. There must be two copies of the DNA so that each daughter cell will have actually a complete copy the the genetic material native the parental cell. Just how is the replicated DNA sorted and also separated so the each daughter cell it s okay a complete collection of genetic material? to answer that question, you very first need to know much more about DNA and the forms it takes.


Figure (PageIndex3): Mitosis is the step of the eukaryotic cell cycle the occurs between DNA replication and also the development of two daughter cells. Mitosis has 4 substages, prophase, metaphase, anaphase, and also telophase.

The blue lines are spindles, and the orange rectangles in ~ the cabinet poles room centrioles. Part spindles from the the contrary centrioles attach with every other, and some spindles attach to the kinetochores of the sisters chromosomes from their particular sides. Every chromosome is enclosed to two spindles.


During anaphase, sister chromatids separate and the centromeres divide. The sister chromatids are pulled apart by the shortening that the spindle fibers. This is a tiny like reeling in a fish by shortening the fishing line. One sister chromatid move to one pole of the cell, and also the various other sister chromatid moves to opposing pole (see figure (PageIndex6)). In ~ the finish of anaphase, each pole of the cell has actually a complete set of chromosomes
