Promoter assays

Promoter assays are scientific tests used to study how genes are turned on or off. They analyze specific DNA sequences called promoters, which are like switches controlling gene activity. By attaching these promoters to a measurable marker, such as a reporter gene, scientists can observe how different factors influence gene expression. This helps researchers understand gene regulation processes, identify elements that control gene activity, and develop therapies or improve genetic engineering techniques. Essentially, promoter assays provide insight into the mechanisms controlling when and how genes are active within cells.
