ABSTRACT
The genetic background of individuals is recognized as an important clue in the analysis of classical hereditary and multifactorial acquired diseases. This new concept derives from the development and increasing use of molecular genetics in clinical medicine. The application of molecular biology techniques in biomedical investigation has encompassed the identification of the pathogenesis and etiology of diseases, prenatal diagnosis the production of new therapeutic agents, gene therapy and the development of pharmacogenetics. The impact on the fundamentals and practice of clinical medicine that will have the use of molecular biology is analyzed in this review

Through the advancements of molecular genetics, physicians and researchers are in an extraordinary period of study concerning the molecular basis of medicine. Molecular biology is making a tremendous impact on both diagnosis and treatment of diseases through the clinical introduction of molecular methods. These techniques, restricted for many years to basic biological research, include the polymerase chain reaction, DNA and protein electrophoresis, cloning of genes into viral or bacterial vectors and methods to rapidly sequence DNA and identify mutations. In this article the authors attempt to provide basic concepts on these themes for the non-trained physicians in order to help them to understand recent developments and foresee their future implications
