Question
5. Chromosomes divide at the centromere during which of the following stages? Choose the most complete answer.A. Anaphase I of meiosisB. Anaphase II of meiosisC. Anaphase of mitosisD. A and CE. B and C
Solution
The correct answer is E. B and C.
During Anaphase II of meiosis and Anaphase of mitosis, the chromosomes divide at the centromere.
In Anaphase I of meiosis, the homologous chromosomes separate but the sister chromatids (the two identical copies of a chromosome that are joined at the centromere) do not separate. This is why option A is not correct.
In Anaphase II of meiosis and Anaphase of mitosis, the sister chromatids separate, meaning the chromosomes divide at the centromere. This is why options B and C are correct.
Therefore, the most complete answer is E. B and C.
