In what phase do the chromosomes duplicate
WebWhat happens during S phase of interphase quizlet? S phase. DNA replication occurs during S phase. Each chromosome is duplicated and thereafter consists of two sister chromatids (the products of DNA replication). The sister chromatids remain joined together until mitosis, when they segregate into two daughter cells. WebCells with too few or too many chromosomes usually don’t function well: they may not survive, or they may even cause cancer. So, when cells undergo mitosis, they don’t just divide their DNA at random and toss it …
