LEARNING OUTCOMES

Aim of the course:
The theoretical lectures and the laboratory exercises of the course introduce students to the basic concepts, principles and methods of molecular biology used in laboratories providing services to the public and in research protocols. The lectures and the laboratory exercises will operate simultaneously as much as possible and the monitoring of students’ knowledge and progress will be provided by multiple choice tests and feedback during the laboratory exercises. Students upon the end of the course should have obtained the knowledge and expertise to attend special background courses and laboratory exercises in the following semesters, as well as to know and understand both the basic concepts of molecular biology and the theoretical and practical background of the basic methods of molecular biology. Students after the end of the semester, must have acquired good theoretical and practical knowledge of modern methods.
