This process is important in single-celled eukaryotes, as it is the process of asexual reproduction. In multi-celled eukaryotes, mitosis is how a single zygote can become an entire organism.
WebJul 30, 2024 · Control of the Cell Cycle. The length of the cell cycle is highly variable, even within the cells of a single organism. In humans, the frequency of cell turnover ranges from a few hours in early embryonic development, to an average of two to five days for epithelial cells, and to an entire human lifetime spent in G 0 by specialized cells, such as cortical … WebThe cell cycle describes an orderly sequence of events that are highly regulated. In eukaryotes, the cell cycle consists of a long preparatory period (interphase) followed by mitosis and cytokinesis. Interphase is divided into three phases: Gap 1 (G 1 ), DNA synthesis (S), and Gap 2 (G 2 ). Interphase represents the portion of the cell cycle ...
