Learning Objectives

Integrated study of cells and living organisms, with emphasis on the basic mechanisms involved in the following processes: duplication and transmission of genetic information and its expression, development, differentiation, cell proliferation, biogenesis of organelles and cellular structures, interactions among cells, biomolecular bases of behavior and evolution. The applications of this knowledge to Medicine and Biotechnology are a relevant aspect of this field. Learning of all advanced biological technologies, including recombinant DNA technology and the use of transgenic animals, is essential to achieving the stated objectives.
