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). Webhereditary material duplicates itself. Upon examination, a cell is found to have twice as much DNA as the normal diploid state but is no longer in the process of replicating the DNA. All of the DNA is found within a single nucleus. Which stage of the cell cycle is this cell in? G2 During which stage of the cell cycle do the chromosomes duplicate?

WebThis occurs by undergoing DNA replication (in S phase during interphase) where the monovalent chromosome is duplicated so that it will have two DNA strands that are replicas of each other. These two strands are each now called a sister chromatid, and the two sister chromatids make up a divalent chromosome.
