WebThe cell cycle is an ordered series of events involving cell growth and cell division that produces two new daughter cells. Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produces two identical (clone) cells. WebIn bacteria, cell growth and DNA replication takes place throughout most of the cell cycle. In eukaryotes, the cell cycle is more complex and consists of 4 distinct phases, i.e., cell growth, DNA synthesis, and replicated chromosomes are distributed by complex series of events preceding cell division. WebDuring which phase of the cell cycle does DNA duplication, or replication, take place? Interphase Correct DNA replicates during interphase. This process provides each new daughter cell with a full complement of genetic material. When a double helix of DNA is replicated, two complete helices are formed. colleen rainey

WebBinary Fission in bacteria starts with DNA replication at the replication origin (a special DNA sequence) near the midpoint of the cell. New replication forks can form even before the first cell division ends; this phenomenon allows an extremely rapid rate of reproduction. Source: http://biology.kenyon.edu/courses/bi...01/week01.html WebThe cell cycle diagram on the left shows that a cell division cycle consists of 4 stages: G1 is the period after cell division, and before the start of DNA replication. Cells grow and monitor their environment to determine whether they should initiate another round of cell division.
