AP BIOLOGY

Detailed explanation-1: -In metaphase II, the chromosomes line up individually along the metaphase plate. In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell.

Detailed explanation-2: -During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells. Then in anaphase II, the chromosomes separate at the centromeres. The spindle fibers pull the separated chromosomes toward each pole of the cell.

Detailed explanation-3: -During anaphase I, the homologous chromosome pairs separate and are pulled to opposite poles of the cell by spindle fibers attached to the centrioles. This first cell division process is completed during telophase I.

Detailed explanation-4: -In metaphase II of meiosis, and metaphase of mitosis, chromosomes line up along the metaphase plate due to the action of microtubule spindle fibers emanating from the centrosomes located at opposite cell poles. These fibers are attached to the chromosomes by kinetochores at the centromeres of the chromosomes.

Detailed explanation-5: -Answer and Explanation: The above statement, “Homologous pairs of chromosomes line up at the metaphase plate during metaphase II” is a true statement.
