Site-specific labeling is a technique used in various fields, including biology and environmental science, to identify and mark specific locations or features within a particular site. This method helps researchers and professionals track changes, monitor conditions, and manage resources effectively. By using unique labels, they can easily reference and analyze data related to specific areas. In the context of genetic engineering, site-specific labeling can also refer to the targeted modification of genes within an organism's DNA. This allows scientists to study gene function and regulation more precisely, leading to advancements in fields like medicine and agriculture.
