Multiple Choice

What is the primary role of the centromere during mitosis?

It forms the nuclear envelope around the chromosomes.

It serves as the attachment site for spindle fibers, ensuring proper segregation of sister chromatids.

It initiates DNA replication before cell division begins.

It synthesizes ribosomal RNA for protein production.

Verified step by step guidance

Understand the context of the question: The centromere is a specific region of a chromosome that plays a critical role during mitosis, a process of cell division.

Recall the function of the centromere: The centromere is the site where the kinetochore forms, which is essential for the attachment of spindle fibers (microtubules).

Relate the centromere's role to mitosis: During mitosis, spindle fibers attach to the kinetochores at the centromeres to ensure that sister chromatids are pulled apart and segregated into the two daughter cells.

Eliminate incorrect options: The centromere does not form the nuclear envelope, initiate DNA replication, or synthesize ribosomal RNA. These functions are unrelated to the centromere's role in mitosis.

Conclude the correct answer: The primary role of the centromere during mitosis is to serve as the attachment site for spindle fibers, ensuring proper segregation of sister chromatids.
