The Molecular Biology course aims to provide the students with the basic knowledge on the structure, organization and replication of the genetic material, the type of information contained in the genome, the mechanisms of transcription and translation, the regulation of these processes, and the structure and function of proteins and other biomolecules. In parallel, and strongly supported by the laboratory component of the course, aims to provide knowledge about basic molecular biology techniques.
The students should acquire basic knowledge on the Molecular Biolog field, and develop the skills needed for the implementation, analysis and interpretation of results derived from the use of basic molecular biology techniques.

Laboratory classes
Introduction to the basic techniques of molecular biology. Material and laboratory safety rules. Preparation of solutions. Isolation and quantification of DNA. Digestion of DNA with restriction enzymes. Polymerase chain reaction (PCR). Separation of DNA fragments by agarose gel electrophoresis. Competent cells and transformation of Escherichia coli with the plasmid pGLO. Regulation the ara operon, and expression of the green fluorescent protein in E. coli.
This discipline is organized in two lectures per week, of one hour each, and laboratory classes of 1,5 hours per week. For pratical reasons the laboratory classes are arranged in blocks of three hours every other week. The lectures are intended for all students attending the course. The presentations are accompanied by the projection of images that illustrate conveniently the subjects, and when possible, with animations. The students should complement the lectures by consulting bibliography: textbooks, websites, and carefully selected scientific articles. For the laboratory classes, it will be provided a practical guide containing the experimental procedures, as well as the program and the schedules.
