During Anaphase I of meiosis, which structures are separated and pulled toward opposite poles of the cell?

• A. Homologous chromosomes
• B. Centromeres
• C. Nucleoli
• D. Sister chromatids

Answer: (A)

Verified step by step guidance

1. Recall the key events of meiosis, focusing on the stages and what happens during each phase, especially Anaphase I.
2. Understand that meiosis consists of two divisions: Meiosis I and Meiosis II, each with distinct separation events.
3. During Anaphase I, homologous chromosomes (each consisting of two sister chromatids) are separated and pulled toward opposite poles of the cell.
4. Centromeres do not separate during Anaphase I; instead, sister chromatids remain attached at their centromeres until Anaphase II.
5. Nucleoli are not involved in chromosome separation; they typically disappear during prophase and reappear in telophase.
