Learning objectives
This course aims to provide students with the basic knowledge of fundamental characteristics of living organisms. In particular, it aims to provide students with the basic knowledge of fundamental biological structures - biological molecules, cells, tissues - and their functioning.
Expected learning outcomes
At the end of the course, students will gain knowledge of the main inorganic and organic components of living organisms, nucleic acid and protein synthesis and related basic regulation, the main functions of nucleic acids and proteins, and transmission of information from DNA to proteins, both in prokaryotic and eukaryotic cells. Students will also gain knowledge of the molecular organization and functions of subcellular organelles and membrane systems in both prokaryotic and eukaryotic cells as well as cell division processes of eukaryotic cells.
Course syllabus and organization

Single session

Responsible
Lesson period
First semester
TEACHING METHODS
The educational activity of the course will be provided as frontal teaching and distance teaching (in synchronous modality). The presence in the classroom will be possible in shifts in compliance with anti-covid regulations.
The methods and criteria for participating in the lessons in attendance, which require a reservation with a special app, will be published on the Ariel pages of the teaching and/or by the teaching secretary of the course.
In case of a new suspension of frontal lessons, all students will be asked to switch to synchronous distance learning. Each hour of the lesson will be divided into 45" formal teaching followed by 15" discussion / interaction / question time.
All lectures will be recorded and available to students on dedicated platforms (e.g. Ariel, TEAMS, etc.).
The lab sessions, while respecting the reported program, will be administrated remotely and the useful material will be available, also as registration provided by the teacher, on the dedicated platforms made available by the University.
Any notice regarding updates or also related to the evolution of the regulations imposed by Covid-19 will be published on the degree course Ariel website and on Ariel website of the individual courses as well as communicated by the teaching secretariat.

TEACHING RESOURCES
The program and reference material will not be changed. The latter will be made available on dedicated platforms (e.g. Ariel, TEAMS, etc.)

ASSESSMENT METHODS AND CRITERIA
Unless otherwise specified, the exams will be organized in the classroom and according to the reported learning methods. If the student will not be able to reach the exam center due to problems with COVID, other modalities may be considered (this applies only to exams scheduled until 31 December - 2020)
