Centromere splits during the _______ stage of meiosis.
Open in App
Solution
The correct option is A anaphase II
Centromere is the structure which holds the sister chromatids of a chromosome together.
The centromere splits during anaphase II of meiosis II when the sister chromatids are pulled apart to the opposite poles of the cells by the spindle fibers.
In metaphase I of meiosis I, the bivalent chromosomes align at the equatorial plate. The spindle microtubules attach to the kinetochore of the homologous chromosomes.
In anaphase I of meiosis I, the homologous chromosomes are pulled apart by the spindle microtubules to the opposite poles of the cell.
In metaphase II of meiosis II, the chromosomes align at the equatorial plate. The spindle microtubules attach to the kinetochore of the sister chromatids.
