Verified step by step guidance

Understand the concept of cell division: Cell division is a process by which a parent cell divides into two or more daughter cells. It is essential for growth, reproduction, and repair in organisms.

Identify the key structures involved in cell division: During cell division, particularly in mitosis, chromosomes are replicated and consist of two identical copies called sister chromatids.

Learn about the centromere: The centromere is a region on a chromosome that joins two sister chromatids. It is crucial for the proper segregation of chromosomes during cell division.

Differentiate between sister chromatids and homologous chromosomes: Sister chromatids are identical copies of a single chromosome, attached at the centromere. Homologous chromosomes are pairs of chromosomes, one from each parent, that are similar but not identical.

Recognize the correct answer: In the context of the problem, the structures attached to each other at a centromere are sister chromatids, not nucleotides, ribosomal subunits, or homologous chromosomes.
