Molecular biology and genomics

Course objectives

General skills The new generation of sequencing technologies has provided unforeseen chances for high-throughput functional genomic studies. These technologies have been applied in a variety of contexts, including whole-genome sequencing, discovery of transcription factor binding sites, mapping out the DNA accessibility and RNA expression profiling. Intriguingly, recent annotation efforts focused on the discovery of novel noncoding RNA genes and regulatory elements that control temporal or spatial gene expression along cell differentiation. The course of Molecular Biology and Genomics is designed to provide students with an introduction to the structure and function of genomes and transcripts in humans and in other model organisms. Topics discussed will include modern genome sequencing technologies, as well the recent in silico and in vivo approaches used for functional genomics and for the functional role of emerging non-coding RNA classes (practical examples taken from recent literature will be used). The course also provides students with basic knowledge for accessing browsers and public databases for the analysis of gene expression data, GO and miRNA target prediction software. By the end of the course, students will be able to apply the acquired knowledge to the study of the basic mechanisms of gene expression, as well as of complex processes such as development, cell division and differentiation, and to exploit them for a practical use in both basic and applied research. Specific skills The students who have passed the exam will be able to know and to understand (acquired knowledge) - the origin and the maintenance of the biological complexity; - the structure and function of the genome in humans and in the main model systems; - the problems and technologies of genome-wide analyses applied to biological processes; - the influence of the modern sequencing technologies for a better description and for the study of transcriptome dynamics in humans and in the main model systems; - the network of interactions between the biological molecules in the mechanisms of regulation of gene expression. The students who have passed the exam will be able to (acquired expertise): - interpret the biological phenomena in a multi-scale and multi-factorial context; - interpret the results of genomic studies and to discriminate which techniques to apply according to the different problems to be dealt with in the genomic field; - report works already present in the literature in the form of an oral presentation.

Prerequisites
The course of Genomics is taught in the second semester of the 3rd year of the 3-year courses in Bioinformatics and it is included among the elective courses. Basic prerequisites for understanding the topics covered by the course are a basic knowledge of Molecular Biology and Genetics. The oral and written comprehension of the English language is essential to take advantage of the oral presentations and the scientific articles proposed by the teachers as didactic material in addition to textbooks.
Books
Textbooks at student’s choice among the followings: - R.F. Weaver Molecular Biology, Mc Graw Hill, V Edition - Watson J.D. et al Molecular Biology of the Gene, Zanichelli VII Edition - Arthur M. Lesk 2009, “INTRODUZIONE ALLA GENOMICA”, Zanichelli - Greg Gibson, Spencer V. Muse 2004, “INTRODUZIONE ALLA GENOMICA”, Zanichelli - Tom Strachan, Judith Goodship, Patrick Chinnery 2016, “GENETICA E GENOMICA”, Zanichelli Update of the texts or teaching material are distributed by the teacher on the web course page: https://elearning.uniroma1.it/course/view.php?id=4530
Teaching mode
The course is structured in frontal theoretical lectures and computer exercises. In particular, there are 48 hours of total teaching (6 CFU). Lectures are held 3 times per week and presented by the use of slides on Power-Point. On the basis of the acquired knowledge, students will present articles already published in literature in the form of oral presentations, individually or in teams. Lessons will be delivered in Aula Psicologia II (CUO26, E01PS1L084) in blended mode. More information is available on the e-learning page of the course: https://elearning.uniroma1.it/course/view.php?id=4530
Frequency
Lectures are not mandatory.
Exam mode
The exam aims at verifying the level of knowledge and in-depth examination of the topics of the teaching program and the reasoning skills developed by the student. The evaluation is expressed in thirtieths (minimum grade 18/30, maximum mark 30/30 with summa cum laude). The evaluation consists of an oral interview conducted by the reference teacher on the topics covered during the course. The overall exam allows verifying the achievement of the objectives in terms of knowledge and skills acquired, as well as communication skills. During the oral tests property of language, clarity of exposition and critical capacity to solve genomic problems are also evaluated. Part of the exam consists of a practical computer test to evaluate the candidate's ability to apply the skills acquired in the consultation of biological databases. The time required for the tests is 30 minutes for oral interviews and 15 minutes for the practical computer test. The final grade will result from the average between the two oral tests and the practical computer test.
