Molecular Biology
A.Y. 2024/2025
Learning objectives
The course aims to provide fundamental knowledge of the molecular mechanisms which regulate and underlie the maintenance and flow of genetic information within prokaryotic and eukaryotic cells. Furthermore, it is designed to offer students an overview of the main molecular biology techniques useful for experimental medicine and/or medical diagnosis.
Expected learning outcomes
In-depth knowledge of the main mechanisms of molecular biology (replication, transcription, transcript maturation, translation, and repair) and their regulation.
Good understanding of the key experiments which have been instrumental in achieving the current knowledge in molecular biology.
Knowledge of the main molecular biology techniques useful in basic and applied research for studying molecular mechanisms.
Ability to apply the acquired theoretical knowledge to correctly design simple molecular and cellular biology experiments (always including appropriate positive and negative controls) and to theoretically solve specific biological problems.
Critical discussion and evaluation of the possible outcomes arising from a biological problem.
Ability to present acquired knowledge clearly and using scientifically accurate language.

Course syllabus
Frontal teaching:
Biological macromolecules: structure and function of DNA, RNA, proteins.
Model organisms for molecular biology studies and methods to generate a model.
Main molecular biology techniques for DNA, RNA and protein analysis and their manipulation (nucleic acid hybridization, Southern, Northern and Western blot, in situ hybridization, DNA sequencing, HIC, IP, ChIP, transcriptome analysis, EMSA and footprinting).
DNA topology and topoisomerases.
Chromatin condensation in eukaryotes: structure of nucleosomes and higher levels of condensation.
Epigenetics: basic concepts (DNA methylation, post-translational modifications of histones and the hypothesis of the existence of an histone code). Role of epigenetics in human health.
Transcription in prokaryotes: structure of the transcriptional apparatus, promoters and regulation mechanisms.
The transcription cycle.
The lactose and tryptophan operon.
Transcription in eukaryotes: structure of transcriptional systems, promoters and regulation mechanisms. Particular emphasis will be given to class II transcription.
Non-RNA coding: synthesis and function.
Overview of RNA editing.
RNA splicing: molecular mechanisms.
Translation in prokaryotes and an overview on the differences with eukaryotes.
DNA replication in prokaryotes and eukaryotes.
Notes on the mechanisms of onset of mutations and DNA repair.
Practical activity:
The students will work in groups of 4/5 students and develop, in a theoretical way, a research project up to the elaboration of a classroom presentation.

Prerequisites for admission
Students must have fulfilled all the prerequisite requirements indicated in the study plan: General and cellular biology, Genetics.
Teaching methods
Most of the course consists of lectures. During the lessons, students are encouraged to try to find experimental strategies useful for solving small scientific problems or for critically analyzing the results of some experiments.
The teaching material consisting of presentations in PDF format that is made available at the end of the lesson on the myAriel platform.
Course attendance is required.
An activity involving practical exercises is also planned, during which an innovative teaching method, Team-Based Learning, is implemented. Students, divided into small groups, are required to theoretically carry out a research project, applying the knowledge acquired during the course and outlining the experimental procedures necessary to solve the scientific problem. In the form of a poster, students must present to their peers and the professor obtained results and the methods used.

Assessment methods and Criteria
The level of learning is assessed only at the end of the course, without any intermediate or preliminary exams. The first three exam sessions consist of a written test lasting one and a half hours, during which students must answer multiple-choice or short-answer questions. For multiple-choice questions, with five possible options, it will be specified whether there is only one or multiple correct answers. The results of the test will be communicated electronically through the official UNIMI platform, and students can accept or reject the grade.For subsequent sessions, the exam is oral. The oral exam is generally organized into two parts. In the first part, students are asked two or three questions aimed at assessing their knowledge of the main topics covered in class (including the exercises). In this phase, the accuracy of language, the ability to organize a linear argument, and overall presentation skills are also evaluated.The second part of the oral exam is typically reserved for students who have demonstrated a good grasp of the subject matter. In this phase, students are asked to solve a specific scientific problem using the molecular biology techniques explained in class. This more complex phase aims to evaluate the student's ability to explore the breadth of molecular biology and its methodological approaches, making diverse use of the concepts learned during the course.In this phase, the student's understanding of how to properly design an experiment—including necessary controls and, when required, appropriate internal standards—is also assessed. The evaluation will be communicated at the end of the exam.
