Learning outcomes This course unit gives students an overall perspective in molecular biology and its applications, with a strong practical component, in order to acquire skills in scientific research, molecular diagnosis, and forensic science.
By the end of this course the students must be able:
1–To describe the chemical and biological bases underlying the techniques of molecular biology and their practical application;
2–To describe the techniques for isolation and manipulation of nucleic acids;
3–To describe the methods for analysis of gene expression and its applications;
4–To execute the main techniques of molecular biology: DNA isolation, PCR, agarose gel electrophoresis, restriction and cloning;
5-To integrate the advanced concepts of molecular biology and to apply them to forensic sciences and to molecular diagnostic, planning experiments with critical spirit.

Teaching Methodologies and Assessment Criteria In theoretical classes, oral exposure of the subjects will be done using data-show, with an intense student-teacher
interaction. In order to ensure participation and motivation of the students, the debate between students and the
teacher will be encouraged. In the laboratory, students will have the opportunity to perform the basic techniques of
molecular biology, which enable them to understand all the applications. They also will solve practical exercises related
to the subject taught in theoretical classes.
• Theoretical component (80% = 16 points).Corresponds to the results obtained in two written tests, 8 points each
(excluding: average <6 points)
• Practical component (20% = 4 points). Corresponds to the laboratory performance and to a written report
about the laboratory work .
Regular attendance: 70% in theoretical classes, 90% in practical classes.
Language Portuguese. Tutorial support is available in English.
