Contents

Biotechnology Competences - Knowledge and understanding of the structure and biological properties of cells,animal and plant tissues; general mechanisms of transmission of hereditary characters;

Reference texts

Molecular cell biology, Bruce Alberts, Alexander Johnson, Julian Lewis, Martin Raff, Keith Roberts, Peter Walter

Educational objectives

The aim is to provide students of basic knowledges of: - structure and function of biological macromolecules: DNA, RNA and proteins; - basic biological functions of the cell.

Prerequisites

Student must have general knowledge of biology, anatomy and chemistry acquired in the school curriculum

Teaching methods

Lectures will be made by using slides and movies. Some lessons will be dedicated to revision and deepth issues also proposed by the students, with the involvement of the students themselves.
Practical lessons will be held in the laboratory and will focus on basic techniques of cell culture

Other information

Attività di didattica integrativa:
It is planned a tutorial activity during the course and for students who request help in the preparation of the exam. The dates of receipt students are available in the professor's website.

Learning verification modality

They consist of a written test followed by an oral test. In the written test (max 2 hours time long) students have to answer to thirty multiple-choice questions and to two questions with a short open answer. This text will be used to verify the level of knowledge acquired.
The oral exam is only for students who pass the written exam with a score equal to or greater than 18/30. This test will allow to resolve gaps emerged on written test and to check their communication ability, proper scientific language and autonomous capability of the presentation of topics of the course. The final score will consider both written and oral exams.
Students, who have not passed the written test, will have the possibility to discuss about their problems with the teacher, the day of the oral examination.

Learning verification modality

Oral examination.
The exam grade will be given by the average of the grade of the General Biology module and that of Cytology and Histology.
During the course two ongoing tests will be carried out in order to ascertain the level of knowledge and understanding of the topics covered during the course and will last a maximum of two hours, during which the student will have to answer forty multiple choice questions.

Educational objectives

The Module of Histology and Embryology examine basic knowledge concerning the structure and function of normal cells, tissues and organs. The course also describe the processes of gametogenesis, fertilization and the early stages of embryogenesis providing the basis for understanding the mechanisms of vertebrate embryonic development. The main aims of the Modulo are: a) to provide a basic understanding of the structure and function of a range of human cells, tissues and organ systems; b) to provide knowledge required for use of light and transmission microscopes; c) to provide basic knowledge concerning the principal steps of embryonic development and the general mechanisms of transmission of hereditary characters;; d) to improve students’ written and oral communicative skills, through the use of correct scientific terminology. With the integrated study of Histology and Embriology, the learning goal for the student is to understand the basic mechanisms of cell differentiation, histogenesis and embryogenesis. The main competence acquired will concern the ability of the student to identify cells and tissues, and to discuss the functional aspects directly associated to specific morphological organization. Through the study of embryonic development, the student will acquire the knowledge to describe the modifications of primitive embryonic layers, until to the outline of originating organs.

Prerequisites

In order to be able to understand the course with highest profit, student must have general knowledge of biology, anatomy and chemistry acquired in the school curriculum

Teaching methods

The course is organized as follows:
-Theoretical lessons with audiovisual material;
-Observation of plastic models.

Other information

Lectures: October-December 2022, Monday and Thursday (4:00PM-6:00PM). Polo di Biotecnologie, Via del Giochetto
- Course attendance is optional but strongly advised.
- The timetable and venue for the lectures, the calendar of exam sessions and of written test will be published on the University website, in the online page of Department of Chemistry, Biology and Biotechnology.
- Students can enroll for the final exam exclusively using the procedures provided by the ESSE3 system.

Learning verification modality

During the course the exam can be carried out in two parts: 1) one or two written tests in itinere concerning the topics already developed; 2) an oral test concerning the remaining part of the program. The written exam , consisting of at least 20 quizzes (2 open questions, some short-answer questions and multiple choice questions), is considered to have been passed with a score of 18/30 or more. The final score will take into account both written and oral exams
For those who have not taken or passed the written exam in itinere, the evaluation method will consist of an oral exam concerning the full program of Histology and Embriology: during the interview, questions will be asked concerning three topics of Histology and one topic of Embryology. In the evaluation of the exams and in the assignment of the final score, the level of knowledge and the ability to integrate contents, the ability to synthesize, as well as the terminology and language skills will be taken into account.
