Mitosis is an incredible process with precise steps and regulation. Without mitosis, life would be impossible. However, the process can seem a bit complex. To begin, let’s explore the different stages of mitosis. Prophase is the first stage of mitosis. In prophase,
Prometaphase is the second stage of mitosis. In prometaphase,
Metaphase is the third step in mitosis. In mitosis,
Anaphase is the fourth step in mitosis. In anaphase,
Telophase is the fifth step in mitosis. In telophase,
Cytokinesis is the sixth and final step of mitosis. In cytokinesis,
MitosisNow that we’ve reviewed each of the steps, let’s look at the cycle as a whole:
In prophase, the nucleolus disappears and chromosomes condense and become visible. In prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores. In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles. In telophase, chromosomes arrive at opposite poles, and nuclear envelope material surrounds each set of chromosomes. Finally, in cytokenesis, the two daughter cells are separated. Let’s take a quick quiz to review what we’ve just learned!
Which of the following options shows the correct order of the steps of mitosis?
What step of mitosis is shown here? What step of mitosis is shown here? Which step does the following passage describe? The kinetochores appear at the centromeres, the mitotic spindle microtubules attach to kinetochores, and the centrosomes move toward opposite poles. What occurs during anaphase?
