Learning outcomes
The aim of this course is to give the students the basic knowledge of the molecular mechanisms concerning transmission, variation and expression of the genetic information.
Program
Theory:
-> Genetic information and informational molecules
General introduction and historical hints. The chemical structure of DNA and RNA. Three dimensional structure of DNA. Physico-chemical properties of DNA.
-> Molecular Biology techniques
Agarose gel electrophoresis. Nucleic acid hybridization. Polymerase chain reaction (PCR). Restriction endonucleases. Cloning and sub-cloning. gene expression systems.
-> DNA, RNA and gene structure
Definition of gene coding and regulatory regions. From genes to proteins; messenger RNA, transfer RNA and ribosomal RNA.
-> Genome organization and evolution
DNA content and number of genes. Mutations, DNA rearrangement and genome evolution. The organelle genomes. Interrupted genes; introns. cDNA. Gene families and duplication. DNA repeats.
-> Transposable elements
Transposition mechanisms and control. Retroviruses and retrotransposones. Transposons.
-> Chromatin and chromosomes
Nucleosomes, histones and their modifications. Higher organization levels of chromatin. Heterochromatin and euchromatin. Eukaryotic chromosomes, telomeres and centromeres.
-> DNA replication
DNA polymerases. Proofreading activity of DNA polymerases. Replication mechanism in bacteria and eukaryotic cells.
-> Introns and RNA splicing
Features of spliceosomal introns. Spliceosome and splicing mechanism. Alternative splicing and trans-splicing. Other kinds of introns: group I and group II introns and tRNA introns. The intron movement. RNA editing. Ribozymes and riboswitch.

-> RNAs and transcription
Different types of RNA: synthesis and maturation. Bacterial RNA polymerase. Sigma factors. Eukaryotic RNA polymerases. Eukaryotic mRNAs: capping, polyadenylation, cytoplasmic localization. The transcription process in bacteria and in eukaryotic cells.
-> Translation
Ribosomes. tRNA structure and function. Aminoacyl-tRNA synthesis. Initiation in bacteria and eukaryotic cells. Polypeptide chain synthesis and translation end. Regulation of translation.
-> Protein localization.
One credit of the course (corresponding to 8 hours) will be kept for the students to discuss an important topic chosen from the research literature in Molecular Biology.
Introduction to the Laboratory Course:
-> Nucleic acids isolation: basis, comparison of several extraction protocols, nucleic acids isolation troubleshooting.
-> Nucleic acids electrophoresis: agarose gels, polyacrylamide gels, denaturing and non-denaturing gels, Pulsed-field gel electrophoresis.
-> Spectrophotometric quantitation of isolated nucleic acids.
-> PCR
1.What is PCR?
2. Reagents: efficiency, specificity, fidelity
3. PCR cycle. Final number of copies of the target sequence
4.Amplifying the correct product: detection and analysis of PCR products, how to avoid contamination (uracil N-glycosylase, UV, enzymatic treatment), hot start, nested PCR
5. Techniques and applications: 5’RACE-PCR and 3’RACE-PCR, RT-PCR, PCR mutagenesis (deletion of sequences, base substitutions, insertion mutagenesis), modification of PCR products (introduction of restriction sites, adding promoters and ribosome-binding sites), joining overlapping PCR products, quantitative PCR
Experiments:
-> Genomic DNA extraction from different plant tissues. Amplification by PCR of selected genes and visualization of PCR products on agarose gels.
-> Total RNA extraction from prokaryotes (bacteria) and eukaryotes (plants), spectrophotometric quantitation, denaturing gels. Synthesis of cDNA and visualization of cDNA population on gel. 5’ RACE-PCR and 3’ RACE-PCR.
