Questions: During anaphase, what changes take place with chromatids? (1 point) The chromatids are pulled towards different centromeres. The chromatids are pulled towards different centrioles. The chromatids are pulled towards the same centriole. The chromatids are pulled towards the same centromere.

The answer is the second one: The chromatids are pulled towards different centrioles.

Explanation for each option:

1. The chromatids are pulled towards different centromeres.

   • Incorrect. During anaphase, chromatids are not pulled towards centromeres. Instead, they are pulled apart from each other.

2. The chromatids are pulled towards different centrioles.

   • Correct. During anaphase, sister chromatids are separated and pulled towards opposite poles of the cell, where the centrioles are located.

3. The chromatids are pulled towards the same centriole.

   • Incorrect. If chromatids were pulled towards the same centriole, they would not be properly separated, which is not what happens during anaphase.

4. The chromatids are pulled towards the same centromere.

   • Incorrect. Chromatids are originally connected at the centromere, but during anaphase, they are pulled apart towards opposite poles, not towards the same centromere.

Summary: During anaphase, the chromatids are pulled towards different centrioles, ensuring that each daughter cell will receive an identical set of chromosomes.
