Biochemistry is the study of chemical processes within and related to living organisms. It seeks to understand the molecular basis of life processes, such as metabolism, signal transduction, and gene expression. By understanding these processes at the molecular level, biochemists can develop new drugs and therapies to treat diseases, as well as improve our understanding of the natural world.

At the heart of biochemistry is the central dogma of molecular biology, which states that DNA is transcribed into RNA, which is then translated into proteins. This process is crucial to the functioning of cells and the regulation of gene expression. It is through the central dogma that the genetic information contained within DNA is used to create the proteins that make up the structures and processes of living organisms.
