Question

Sister chromatids are

• A. created when DNA is replicated
• B. separated during mitosis
• C. attached at the centromere prior to division
• D. all of these

Answer 1

The correct option is D all of these

The sister chromatids are pair of identical chromatids that are formed during synthesis phase of cell division. These chromatids are joined at a point called the centromere. In simple terms, it can be said that sister chromatids are half of the duplicated chromosomes. Sister chromatids get separated from each other during mitosis stage of cell division.
