An "Enhancer" is a substance or tool that improves the effectiveness or quality of something. In various fields, such as nutrition, cosmetics, or technology, enhancers are used to boost performance or results. For example, in cooking, flavor enhancers like salt or spices can make dishes more enjoyable. In the context of genetics, enhancers are specific DNA sequences that increase the likelihood of transcription of a particular gene. They play a crucial role in regulating gene expression, allowing cells to respond to different signals and adapt to their environment. Enhancers can be found far from the genes they regulate, highlighting their complex role in biology.
