Centromeres Divide In

Question

Centromeres divide in
A) mitosis and meiosis I.
B) mitosis and meiosis II.
C) meiosis II only.
D) meiosis I and meiosis II.
E) mitosis, meiosis I and meiosis II.

Accepted Answer

Centromeres divide during both mitosis and meiosis II. During mitosis, centromeres divide in order to separate sister chromatids, while during meiosis II, centromeres divide in order to separate homologous chromosomes. Centromeres do not divide during meiosis I, as homologous chromosomes remain together.
