Question: when is dna replicated in a cell cycle

title: Cell cycle
text: The cell cycle or cell - division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA ( DNA replication ) to produce two daughter cells . In bacteria , which lack a cell nucleus , the cell cycle is divided into the B , C , and D periods . The B period extends from the end of cell division to the beginning of DNA replication . DNA replication occurs during the C period . The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells . In cells with a nucleus , as in eukaryotes , the cell cycle is also divided into three periods : interphase , the mitotic ( M ) phase , and cytokinesis . During interphase , the cell grows , accumulating nutrients needed for mitosis , preparing it for cell division and duplicating its DNA . During the mitotic phase , the chromosomes separate . During the final stage , cytokinesis , the chromosomes and cytoplasm separate into two new daughter cells . To ensure the proper division of the cell , there are control mechanisms known as cell cycle checkpoints . 

Answer: answer: In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C and D periods. DNA replication occurs during the C period.
