Molecular Biology focuses on DNA and how proteins are made. DNA contains the information used to make RNA. RNA leaves the nucleus and, together with a ribosome, makes proteins. The genetic code is the universal code that all life uses to turn the language of nucleotides into the language of amino acids.

The field of molecular biology studies macromolecules and the macromolecular mechanisms found in living things, such as the molecular nature of the gene and its mechanisms of gene replication, mutation, and expression. Given the fundamental importance of these macromolecular mechanisms throughout the history of molecular biology, a philosophical focus on the concept of a mechanism generates the clearest picture of molecular biology’s history, concepts, and case studies utilized by philosophers of science.

The field of molecular biology arose from the convergence of work by geneticists, physicists, and structural chemists on a common problem: the nature of inheritance. In the early twentieth century, although the nascent field of genetics was guided by Mendel’s laws of segregation and independent assortment, the actual mechanisms of gene reproduction, mutation and expression remained unknown. Thomas Hunt Morgan and his colleagues utilized the fruit fly.
