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.
Centromeres
The region of a chromosome where the two sister chromatids are most tightly connected, playing a vital role in chromosome segregation during cell division.
Mitosis
A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Meiosis I
The first division in meiosis, a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, important for sexual reproduction.

Final Answer :
B
Explanation :
Centromeres divide during mitosis and meiosis II, ensuring that each daughter cell receives a complete set of chromosomes. In meiosis I, homologous chromosomes separate, but the centromere of each chromosome remains intact.
