Web1 mrt. 2024 · The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells. The S phase only begins when the cell has passed ... WebTermination of DNA replication in E. coli is completed through the use of termination sequences and the Tus protein. Tus is a sequence-specific DNA binding protein that promotes termination in prokaryotic DNA replication. In E. Coli, Tus binds to ten closely related 23 basepair binding sites encoded in the bacterial chromosome. WebEach stage of interphase has a distinct set of specialized biochemical processes that prepares the cell for initiation of cell division (see figure below). G1 phase. Interphase begins with G 1 (G stands for gap) phase. During this phase, the cell makes a variety of proteins that are needed for DNA replication. S phase free bdm records
