Learning outcomes

------------------------
MM: BIOLOGIA MOLECOLARE
------------------------
To understand the fundamental processes of the science of DNA and the flow of information that leads from DNA to RNA to proteins. To understand mechanisms, function and regulation of these processes. To educate medical students to the scientific method through the description of experiments that allowed the elucidation of molecular biological mechanisms. To understand recombinant DNA technologies and their potential.

------------------------
MM: GENETICA MOLECOLARE e MM: GENETICA MEDICA
------------------------
The course aims to provide the basic knowledge of the principles and mechanisms of human and molecular genetics responsible for the transmission of normal and abnormal characters in humans, as well as the mode of occurrence of hereditary biological variation.

Professionalizing objectives
The course aims to provide the future doctor with the knowledge and tools necessary to be able to advise the patient and his family in presence of a genetic or hereditary disease, about the nature of the disease, its incidence, prognosis, risks recurrence, preventive options, available therapeutic and reproductive options, and of the available genetic tests, whether diagnostic, symptomatic, predictive, pre- or post-natal. At the end of the course the student should be able to ask the appropriate questions to draw and interpret human pedigrees, distinguish different types of inheritance, request genetic tests to confirm (or exclude) a suspected genetic disease and interpret their results, knowing how to efficiently counsel patients and families about the nature of genetic disease, as well as to assess recurrence and occurrence of reproductive genetic risks (genetic counselling), indicating possible genetic and environmental causes in multifactorial diseases, enumerating the possible causes and types of gene mutation and be able to derive the frequency of the disease gene/allele frequency in populations.

Assessment methods and criteria

In order to pass he whole exam, students should demonstrate to have learned the necessary knowledges listed in the programme, e to demonstrate skills in exposing thei arguments in a critical and precise way, using an appropriate scientific language.
Each academic year includes 6 exam sessions, arranged as follows: two exams in the winter session, at the end of the Course, two exams in the Summer session, and two exams in the Autumn session.
Each exam is made of two parts, each part passable separately within the same academic year: Molecular Biology (6CFU) and Molecular/Medical Genetics (tiotal 9CFU). Each part consists of a written test of mutiple choice questions, open questions and exercises, followed by an oral test (provided the written test is passed). The exam is passed if the score in each part is equal to or greater than 18/30; the final cumulative score, in thirtieths (.../30), is calculated from the weighted average of the scores of two modules. Students who pass only one part of the exam are allowed to take the other part only in the next sessions, provided they are within the same academic year.
