Question

If the sister kinetochore is mitotic, what type of alignment do the chromosomes have?

1) Metaphase alignment
2) Anaphase alignment
3) Telophase alignment
4) Prophase alignment

Answer 1

The correct answer is 1. The chromosomes have metaphase alignment when the sister kinetochore is mitotic, meaning that sister chromatids line up along the metaphase plate before they separate during anaphase.

Step-by-step explanation:

If the sister kinetochore is mitotic, the type of alignment that the chromosomes have is metaphase alignment. During metaphase, sister chromatids with their kinetochores attach to spindle fibers and line up at the metaphase plate, which is equidistant from the two poles of the cell.

This alignment ensures that when the sister chromatids separate during anaphase, each new cell will receive an identical set of chromosomes. The specific sequence of events in mitosis involves the kinetochores becoming attached to the mitotic spindle, followed by the alignment of sister chromatids at the metaphase plate. Then, the kinetochores break apart, allowing the sister chromatids to separate, after which the nucleus re-forms around the separated chromatids in each new cell.
