Guida verificata passo dopo passo1
Understand the context of meiosis: Meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells. It consists of two stages: meiosis I and meiosis II.
Recall the events of anaphase II: During anaphase II, the sister chromatids of each chromosome are separated and pulled toward opposite poles of the cell. This is distinct from anaphase I, where homologous chromosomes are separated.
Identify the role of the centromere: The centromere is the region of a chromosome where sister chromatids are held together. During anaphase II, the centromere splits, allowing the sister chromatids to separate.
Eliminate incorrect options: Centrioles are involved in spindle formation but are not pulled apart. Homologous chromosomes and tetrads are separated during meiosis I, not anaphase II.
Conclude that the correct answer is 'Sister chromatids,' as they are the structures being pulled apart at the centromere during anaphase II of meiosis.
