Chromatid and Cell Division Biology Quiz

Questions and Answers

What are sister chromatids?

Chromatids that originate from different homologous chromosomes.

Chromatids that do not separate during anaphase.

Chromatids produced through the replication of a single chromatid during the G1 phase.

Identical chromatids formed during the synthesis phase of interphase. (correct)

What is the role of the centromere in a chromosome?

It is the point where both sister chromatids are joined together. (correct)

It provides structural support to homologous chromosomes.

It allows chromatids to remain separated during mitosis.

It is involved in the replication of chromatids.

During which stage do sister chromatids separate and move towards opposite poles?

Metaphase II of meiosis

Anaphase of mitosis (correct)

Prophase of mitosis

Telophase of meiosis

Study Notes

Chromatid Overview

Metaphase chromosomes consist of two identical parts called chromatids.
The point where the two chromatids are joined is known as the centromere.

Chromatid Separation

Chromatids separate during mitotic anaphase and anaphase II of meiosis.
Upon separation, chromatids move towards opposite poles of the cell.

Sister vs. Non-Sister Chromatids

Sister chromatids are created by the replication of a single chromatid during the synthesis (S) phase of interphase.
Non-sister chromatids refer to the chromatids of homologous chromosomes, which are not identical to each other.
