The cell cycle is the process by which a cell grows, duplicates its DNA, and divides into two daughter cells. It is a highly regulated and coordinated process that ensures the accurate duplication and distribution of genetic material to the daughter cells. The cell cycle consists of several key stages, including interphase, during which the cell grows and prepares for division, and mitosis, where the duplicated DNA is segregated into two daughter cells. Dysregulation of the cell cycle can lead to diseases such as cancer, making it an important area of research in biology and medicine. Scientists study the cell cycle to understand how it is regulated, how it responds to different signals, and how it can be targeted for therapeutic purposes.
