Adenine is widely used in molecular biology and biochemistry research as a fundamental component of DNA and RNA. It plays a critical role in the synthesis of nucleic acids, making it essential for studies involving genetics, cellular processes, and molecular cloning. In addition, adenine is a key building block for ATP (adenosine triphosphate), the primary energy carrier in cells, making it vital for research in metabolism and energy transfer mechanisms. It is also utilized in the production of certain antiviral and anticancer drugs, where its incorporation helps inhibit the replication of viral or cancerous cells. Furthermore, adenine derivatives are employed in diagnostic assays and as markers in various biochemical studies.
