Cellular repair is the process by which cells fix damage to their structures and functions. This can occur due to various factors, including injury, toxins, or normal wear and tear. Cells utilize specialized mechanisms, such as DNA repair pathways, to correct errors and maintain their integrity. In addition to DNA repair, cells can also regenerate damaged components like proteins and membranes. This is essential for overall health, as effective cellular repair helps prevent diseases and supports tissue regeneration. Understanding these processes is crucial for advancements in fields like medicine and biotechnology.
