WebThe cell goes through similar stages and uses similar strategies to organize and separate chromosomes. In meiosis, however, the cell has a more complex task. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis. WebIn the eukaryotic cell cycle, chromosome duplication occurs during "S phase" (the phase of DNA synthesis) and chromosome segregation occurs during "M phase" (the mitosis phase). WebMar 30, 2024 · The chromosomes, each of which is a double structure consisting of duplicate chromatids, line up along the midline of the cell at metaphase.

WebMar 22, 2024 · Right after a cell divides, it has one copy of each chromosome. Soon, each chromosome is replicated, or copied, in preparation for mitosis and another round of cell division. A replicated chromosome (or equivalently, a duplicated chromosome) contains two identical chromatids, also called sister chromatids.

WebSo, when cells undergo mitosis, they don’t just divide their DNA at random and toss it into piles for the two daughter cells. Instead, they split up their duplicated chromosomes in a … WebDuring DNA duplication in the S phase, each chromosome is replicated to produce two identical copies, called sister chromatids, that are held together at the centromere by cohesin proteins. Cohesin holds the chromatids together until anaphase II.
