Extracellular signaling molecules can activate intracellular signaling pathways by binding to specific receptors on the cell surface. The binding of the signaling molecule to the receptor triggers a series of events, collectively known as signal transduction, that ultimately lead to changes in the activity or behavior of the cell. The process of signal transduction typically …

Cell division is the process by which a single cell divides into two or more daughter cells. There are two main types of cell division: Cell division is essential for the growth and development of organisms, as well as for tissue repair and maintenance. In addition, it plays an important role in reproduction by producing …
