Which of the following represents the correct order of the phases of mitosis?

Mitosis is an incredible process with precise steps and regulation. Without mitosis, life would be impossible. However, the process can seem a bit complex. Show  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: Mitosis: In SummaryIn 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! Practice QuizWhich of the following options shows the correct order of the steps of mitosis?
Show Answer Answer a is correct. If you answered b, you might be having some trouble keeping the beginning steps in order. If you answered c, you might be having some trouble keeping the steps in the second half of mitosis in order. What step of mitosis is shown here? Show Answer The cell shown above is in prophase. In prophase, the first step in mitosis, the nuclear envelope breaks down and chromosomes condense and become visible. What step of mitosis is shown here? Show Answer The cell shown above is in metaphase. In metaphase, the mitotic spindle is fully developed, centrosomes are at opposite poles of the cell, and chromosomes are lined up at the metaphase plate. 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. Show Answer This passage describes prometaphase, the second step in mitosis What occurs during anaphase?
Show Answer Answer b is correct. This is one of the events that occur during anaphase. During anaphase, the cohesin proteins binding the sister chromatids together also break down, and the non-kinetochore spindle fibers lengthen, elongating the cell. Answer a occurs during metaphase, which happens before anaphase. Answer c occurs during telophase, which happens after anaphase. What is the correct order for phases of mitosis?These phases are prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis is the final physical cell division that follows telophase, and is therefore sometimes considered a sixth phase of mitosis.
What are the 5 mitosis phases?Mitosis is conventionally divided into 5 phases, which include prophase, prometaphase, metaphase, anaphase and telophase and cytokinesis.
What is the correct order of the phases of mitosis quizlet?Which of the following represents the correct order of the phases of mitosis? Answer: Prophase > Metaphase > Anaphase > Telophase.
What are the 4 phases of mitosis and what happens in each?Prophase – The chromosomes shorten and thicken. Metaphase – Chromosomes line up in the middle of the cell. Anaphase – Chromatids break apart at the centromere and move to opposite poles. Telophase – Two nuclei formed after nuclear envelopes reform around each group of chromosomes.
