The correct answer is anaphase.
A)Which phase of mitosis is characterized by each pair of sister chromatids moving to opposite sides of the cell?(1 point) Responses anaphase anaphase metaphase metaphase prophase prophase telophase
The correct answer is anaphase.
A)In which mitotic phase does the process of cytokinesis conclude?(1 point) Responses telophase telophase interphase interphase metaphase metaphase prophase
The correct answer is telophase.
The stage of mitosis characterized by microtubules pulling replicated chromosomes apart and separating them into sister chromatids is called anaphase. Anaphase is one of the four stages of mitosis, which is the process of cell division. During anaphase, the microtubules, part of the cell's cytoskeleton, attach to the replicated chromosomes at their centromeres and begin to pull them apart. This action causes the chromosomes to separate into two sets of sister chromatids and move towards opposite ends of the cell.
To determine the correct answer to this question, you can recall the different stages of mitosis and identify which one involves the separation of replicated chromosomes. Here is a brief overview of the other stages mentioned in the question:
1. Prophase: This is the first stage of mitosis and is characterized by the condensation of chromosomes, breakdown of the nuclear envelope, and the formation of spindle fibers.
2. Telophase: This is the last stage of mitosis, during which the separated sister chromatids reach opposite poles of the cell, and new nuclear envelopes form around each set of chromosomes.
3. Metaphase: During metaphase, the chromosomes align along the central region of the cell, known as the metaphase plate, and the spindle fibers attach to the centromeres of each chromosome.
By understanding the distinct features of each stage, you can conclude that anaphase is the correct answer to this question.
