cellular and molecular mechanisms

Cellular and molecular mechanisms are processes that occur within cells to keep them functioning. At the molecular level, molecules like DNA store genetic instructions, while proteins carry out tasks such as repairing damage or signaling between cells. Cells respond to their environment by activating these molecules, adjusting internal activities, and communicating with neighboring cells. These mechanisms regulate growth, energy production, and defense, ensuring the body functions smoothly. Essentially, they are the detailed activities that allow living organisms to develop, adapt, and survive.
