Reporter genes

Reporter genes are specific genes used in scientific research to measure and visualize the activity of other genes. They encode easily detectable proteins, such as fluorescent markers or enzymes that produce colored reactions. By attaching a reporter gene to a gene of interest, researchers can track when and where that gene is active in cells or organisms. This helps scientists understand gene regulation, study diseases, and develop new treatments. Essentially, reporter genes act like biological "flags" that signal when certain genetic instructions are being carried out.
