GAL4/UAS System
The GAL4-UAS system is a biochemical method used to study gene expression and function in organisms such as the fruit fly. It was developed by Andrea Brand and Norbert Perrimon in 1993 and is considered a powerful technique for studying the expression of genes. The system has two parts: the GAL4 gene, encoding the yeast transcription activator protein Gal4, and the UAS (Upstream Activation Sequence), an enhancer to which Gal4 specifically binds to activate gene transcription.

Famous quotes containing the word system:
“In the end we beat them with Levi 501 jeans. Seventy-two years of Communist indoctrination and propaganda was drowned out by a three-ounce Sony Walkman. A huge totalitarian system ... has been brought to its knees because nobody wants to wear Bulgarian shoes.... Now they’re lunch, and we’re number one on the planet.”
