Web26 de mar. de 2024 · A variety of genes are involved in the control of cell growth and division. The cell replicates itself in an organized, step-by-step fashion known as the cell cycle. Tight regulation of this process ensures that a dividing cell’s DNA is copied properly, any errors in the DNA are repaired, and each daughter cell receives a full set of … WebEukaryotic Cell Cycle and Mitosis. The cell cycle is an orderly sequence of events used by biological systems to coordinate cell division. In eukaryotes, cell division proceeds via a cell cycle that includes multiple spatially and temporally coordinated events. These include a long preparatory/growth period, called interphase, and a mitotic ...
