You are watching: Which stage of mitosis takes the longest

Divide and also Split

Can you guess what this vibrant image represents? It reflects a eukaryotic bio cell throughout the procedure of cabinet division. In particular, the photo shows the cell nucleus of the cell dividing. In eukaryotic bio cells, the nucleus divides prior to the cell itself splits in two; and before the nucleus divides, the cell’s DNA is replicated, or copied. There need to be two duplicates of the DNA so the each daughter cell will have actually a finish copy of the genetic material from the parent cell. Exactly how is the replicated DNA sorted and separated so the each daughter cell gets a complete set of hereditary material? to answer that question, you an initial need to know much more about DNA and also the develops it takes.

Figure \(\PageIndex3\): Mitosis is the phase of the eukaryotic cell cycle the occurs between DNA replication and also the development of 2 daughter cells. Mitosis has 4 substages, prophase, metaphase, anaphase, and telophase.

The blue lines are spindles, and the orange rectangles in ~ the cabinet poles are centrioles. Some spindles indigenous the the contrary centrioles affix with each other, and some spindles attach to the kinetochores the the sister chromosomes from their particular sides. Every chromosome is fastened to 2 spindles.

Anaphase

During anaphase, sister chromatids separate and also the centromeres divide. The sister chromatids room pulled personally by the shortening that the spindle fibers. This is a small like reeling in a fish by shortening the fishing line. One sister chromatid move to one pole of the cell, and also the other sister chromatid moves to the opposite pole (see number \(\PageIndex6\)). In ~ the end of anaphase, every pole of the cell has a complete collection of chromosomes
