Learning objectives
The aim of this course is to give the student the ability to acquire the basic principles of biochemistry, biology and genetics; learn and apply an evolutionary logic and perspective to interpreting the biological phenomena at different levels of organization (molecular, cellular, organismic); understand the correlation between structure and function at the different organizational levels.

Teaching methods
Interactive class lectures. During classroom lectures the teacher illustrates and discusses the state of the art, concepts and experiments in a specific issue. Students are strongly encouraged to ask questions and insert comments.
Assessment methods and criteria
The achievement of the learning objective described above will be verified by a written test on all the topics of the three modules.
The student will then, after applying online, be expected to take a written exam on the dates of the official exam calendar. The students must obtain at least 18/30 for each module and the final mark will correspond to the arithmetic average of the score obtained in each module.
A grade of 30/30 in all 3 modules will result in the final grade of 30 cum laude.
Exam results are posted on the Esse3 website within one week from the date of the exam, and students will have one week to reject the grade. Students can review the exam by making an appointment with the professor.
Students with DSA/BSE must contact the University's Reception and Inclusion Centre (CAI) in advance and follow the CAI's instructions for any requests for personalised examinations (https://www.cai.unipr.it).
Other information
The slides used to support the lectures will be uploaded weekly to the Elly platform (https://elly2023.medicina.unipr.it). The slides will be available only for the Studenta of the Course: 3044 - Ortottica ed assistenza oftalmologica (abilitante alla professione sanitaria di Ortottista ed assistente di oftalmologia)
