Question

which correctly describes sister chromatids? (1 point) they make up the mitotic spindle within the cell. they form during metaphase when dna is being replicated. they are the daughter cells that form during cell replication. they are part of the lined - up chromosomes in mitosis.

Explanation:

• Sister chromatids are identical copies of a chromosome connected by a centromere.
• During mitosis, chromosomes (with sister chromatids) line up at the metaphase plate.
• Mitotic spindle is made of microtubules, not sister chromatids.
• DNA replication (and thus sister chromatid formation) occurs in S - phase (not metaphase).
• Daughter cells are formed after cytokinesis, not sister chromatids.

Answer:

They are part of the lined - up chromosomes in mitosis.
