You are watching: During which stage of mitosis do the centromeres split

Divide and Split

Can you guess what this vibrant image represents? It shows a eukaryotic bio cell during the process of cell division. In particular, the photo shows the cell core of the cabinet dividing. In eukaryotic cells, the cell nucleus divides before the cabinet itself splits in two; and before the cell core divides, the cell’s DNA is replicated, or copied. There need to be two copies of the DNA so that each daughter cabinet will have a complete copy of the genetic material from the parent cell. Exactly how is the replicated DNA sorted and also separated so that each daughter cell it s okay a complete collection of genetic material? come answer the question, you an initial need come know much more about DNA and also the forms it takes.

Figure \(\PageIndex3\): Mitosis is the step of the eukaryotic cell cycle that occurs in between DNA replication and the formation of 2 daughter cells. Mitosis has four substages, prophase, metaphase, anaphase, and telophase.

The blue lines room spindles, and the orange rectangles in ~ the cell poles room centrioles. Some spindles from the opposing centrioles attach with each other, and some spindles connect to the kinetochores that the sisters chromosomes from their respective sides. Every chromosome is attached to two spindles.

Anaphase

During anaphase, sisters chromatids separate and also the centromeres divide. The sisters chromatids space pulled personal by the shortening that the spindle fibers. This is a small like reeling in a fish by shortening the fishing line. One sister chromatid moves to one pole that the cell, and also the various other sister chromatid move to opposing pole (see figure \(\PageIndex6\)). At the finish of anaphase, every pole the the cell has actually a complete set of chromosomes
