COURSE CONTENT:
1. Physiology of Escherichia coli and the bacterial genome: features of the genome, bacterial genome annotation, naming genes, useful databases on internet
2. Mutations and mutagenesis: types of mutations; spontaneous and induced mutations; types of mutagens; reversion versus suppression, isolating mutants; in vitro mutagenesis. Useful methods for generating mutants in prokaryotes and eukaryotes.
3. Genetic analysis in bacteria: selecting mutants; allelism test; complementation test; epistasis;
4. DNA repair: specific repair pathways (photo reactivation), general repair pathways (nucleotide excision repair, methyl directed mismatch repair), DNA damage tolerance mechanism (SOS inducible repair, translesion synthesis).
5. Homologous recombination in prokaryotes and eukaryotes: molecular models of recombination; the molecular basis for recombination in E. coli; recombination in eukaryotes
7. Plasmids: plasmid structure, properties of plasmids; plasmid replication control mechanisms; plasmid incompatibility;
8. F-plasmid and conjugation: mechanism of DNA transfer during conjugation; formation of Hfr strains and prime factors; genetic mapping by Hfr crosses
9. Mobile genetic elements: transposons and retrotransposons
10. Bacteriophages: lytic and lysogenic phages; general and specialized transduction; site-specific recombination and families of recombinases
11. Lambda phage life cycle: lytic development; phage integration; phage induction
12. Antiviral mechanisms: restriction and modification; CRISPR.
13. Regulatory small RNAs: miRNA, siRNA, piRNA.
14. Heat shock response and chaperons: protein folding; heat shock regulation, the role in cancer
PRACTICAL WORK:
The practical work is structured as a four-week research project aimed at addressing a defined scientific question. The experimental approach varies each academic year and may include techniques such as site-directed mutagenesis, gene cloning, deletion mutant construction, polymerase chain reaction (PCR), plasmid isolation, bacterial transformation, RNA isolation, quantitative PCR (qPCR), or experimentation with bacteriophage lambda. Throughout the practical work, students perform data collection, followed by systematic analysis and interpretation of results during and after the laboratory sessions. The practicum concludes with a written final examination assessing the knowledge and skills acquired during the course.
