Detailed explanation-1: -During prophase I, the chromosomes condense and become visible inside the nucleus. Because each chromosome was duplicated during the S phase that occurred just before prophase I, each now consists of two sister chromatids joined at the centromere.
Detailed explanation-2: -Chromosomes become visible during prophase.
Detailed explanation-3: -Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate.
Detailed explanation-4: -Prophase: the nuclear envelope breaks down, chromosomes condense, and spindle fibers connect to sister chromatids.
Detailed explanation-5: -Meiosis I, the first meiotic division, begins with prophase I. During prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes. The pairs of replicated chromosomes are known as sister chromatids, and they remain joined at a central point called the centromere.
