2. Gene Expression Protein production is a biotechnological process of generating specific proteins. It is typically achieved by the manipulation of gene expression in an organism such that it expresses large amounts of a recombinant gene. The process includes the transcription of the recombinant DNA to messenger RNA (mRNA), the translation of mRNA into polypeptide chains, which are ultimately folded into functional proteins and may be targeted to specific subcellular or extracellular locations. Recombinant proteins are widely used in the life science, biotechnology and medicine and can be achieved by cell-based or cell-free systems. Cell-based systems are the oldest and most widely used expression systems which involve transforming/transfecting cells with a DNA vector that contains target gene and then culturing the cells so that they transcribe and translate the desired protein. Typically, the cells are then lysed to extract the expressed protein for subsequent purification. While, cell-free systems are performed in vitro using translation-compatible extracts of whole cells, including RNA polymerase, regulatory protein factors, transcription factors, ribosomes, and tRNA.
