The main goal of the course is focused in the linkage between student’s integration in a cell and molecular biology laboratory space, together with the practice of selected Cell Biology methodologies.

This objective will be permanently accompanied by training in standard safety lab procedures (in prevention and accident) and by the theoretical and practical foundations of the scientific method and scientific writing. In articulation with TLB II (7624), more centred on molecular biology, this course prepare for specific and more differentiated courses, such as Neurobiology, Developmental Biology and Cell Toxicology.    


Attendance to Introductory Biology and Chemistry for Biologists is strongly encouraged.
