Competent Cells: Definition, Methods, and Applications

A competent cell is a bacterial cell that has been treated to make it more receptive to taking up foreign DNA. This can be achieved through various methods, such as chemical treatment or electroporation. Once the cell is competent, it can be used for genetic transformation experiments, where foreign DNA is introduced into the cell and integrated into its genome. Competent cells are commonly used in molecular biology research, genetic engineering, and biotechnology applications.
