Which stage of mitosis is characterized by microtubules pulling replicated chromosomes apart and separating them into sister chromatids?(1 point)
The stage of mitosis characterized by microtubules pulling replicated chromosomes apart and separating them into sister chromatids is called anaphase.
The stage of mitosis characterized by microtubules pulling replicated chromosomes apart and separating them into sister chromatids is called the metaphase stage.
The stage of mitosis characterized by microtubules pulling replicated chromosomes apart and separating them into sister chromatids is called the "anaphase" stage. To understand why anaphase is the correct answer, let's break down the process of mitosis and the stages involved.
Mitosis is a crucial process of cell division that results in the formation of two identical daughter cells. It consists of several stages, namely prophase, metaphase, anaphase, and telophase. During prophase, the replicated chromosomes condense and become visible. The nuclear envelope breaks down, and the spindle fibers begin to form.
In metaphase, the chromosomes align themselves at the center of the cell, forming what is known as the metaphase plate. At this stage, the microtubules are fully formed and attached to the chromosomes at the kinetochores.
During anaphase, the microtubules start contracting, pulling the sister chromatids apart. This separation leads to the movement of the replicated chromosomes towards opposite poles of the cell. The microtubules that are not attached to the chromosomes elongate and push against each other, causing the cell to elongate as well.
By the end of anaphase, the replicated chromosomes are fully separated into individual sister chromatids and are on their way to opposite poles of the cell. It is crucial for this process to occur accurately to ensure that each daughter cell receives the correct number and type of chromosomes.
Therefore, the correct answer to your question is the anaphase stage of mitosis.
