| Contents | The aim of the course is to provide concepts about acid nucleic and protein structures and problems related to acid nucleic analysis by classical methods (isolation, purification and structural and functional property studies. During the course the students will acquire knowledge about analytical and preparative techniques used in molecular biology studies and practical and theoretical expertise on the isolation and analysis of DNA and RNA molecules. |

| Educational objectives | Biotechnology competence - understanding and knowledge of: i) the structure and biological properties of either virus or bacteria, including genetic modified organisms; ii) molecular basis of transmission and expression of genomes; iii) molecular methods of analysis; iv) techniques of genomic manipulation. Capability to apply knowledge and understanding of: methods of genomic manipulation of cells and animal and plant organisms. |
| Prerequisites | Basic knowledge in the field of organic chemistry, biology, biochemistry and spectrophotometry represent a prerequisite for student planing to follow the course with profit |
| Teaching methods | Lectures, seminars |
| Other information | Attending classes: Recommended but not compulsory |
| Learning verification modality | The exam consists in written and oral examination. The written examinations are designed at evaluating the student's knowledge and understanding of the topics proposed, the ability to work in laboratory and to solve problems. The written exam consists in thirty multiple-choice questions followed by two essays to evaluate the ability to communicate in written form. The students will integrate the written exam with oral examination provided he will obtain at least the minimum mark 18/30. |

| Contents | The aim of the course is to illustrate students the mail topics related to the flux of genetic information from gene to protein, including an analysis at molecular level of the genetic information flux from gene to protein, through an analysis at molecular level of genome maintenance (replication, repair) and expression (transcription and its regulation, translation). In addition, the course has the objective to explain the essential of recombinant DNA methodology and cloning. |

| Educational objectives | Students will study nucleic acid structure and the mechanics of replication, repair, transcription, and translation in prokaryotes and eukaryotes. A central goal is understanding gene expression at all levels, and the structure-function relationships of nucleic acids and proteins. Techniques in molecular biology will be examined in as necessary to understand concepts. |
| Prerequisites | A prerequisite of the course are basic notions on the eukaryotic and prokaryotic cell organization (General Biology), on genetic information flux (General Biology) and on structure/function relationship of the main classes of macromolecules (Biochemistry) |
| Teaching methods | The course is based on i) lessons with slides and ii) practise on DNA methodology application (restriction maps, screening of recombinants) |
| Other information | For the teaching calendar (lessons date and place), please check the Biotechnology course website: biotecnologie.unipg.it |
| Learning verification modality | The final examination will consist in a written test on all topics (90 min, 40 questions with multiple answers) to assess the basic comprehension of the course topics and an oral examination for students with a sufficient evaluation in it (18/30), in order to discuss the critical points emerged. Students that will not reach a sufficient evaluation in the written part (18/30) may discuss the critical points during the oral examination or with the teacher by appointment Students with disabilities or DSA may consult the webpage www.unipg.it/disabilita-e-dsa |
