Course objectives
The aim of the course is to provide students with information on the storage of genetic information for prokaryotes, its implementation, changes and vertical and horizontal transmission. Students should understand the basic terminology of bacterial genetics, genome structure, chromosome replication and plasmids, the use of transposons to analyze genomes and create mutations and mechanisms of evolution of bacteria.
Learning outcomes
Student will be able explain how the genetic information of prokaryotes is maintained, changed and transferred vertically and horizontally. The students should be able to explain the basic terms of bacterial genetics. structure and reproduction of bacterial chromosome, plasmid-borne functions, regulation of plasmid replication, genetics with transposons, the ways of horizontal gene transfer in bacteria and molecular evolution processes of prokaryotic genomes.
  • Terminology of bacterial genetics
  • Structure and reproduction of bacterial chromosome
  • Plasmids (general characteristic of plasmid, plasmid-borne functions, regulation of plasmid replication, plasmid stability, plasmid incompatibility and recombination)
  • F plasmid, R plasmids, Col plasmids, Ti plasmids of Agrobacterium tumefaciens
  • Prokaryotic transposons, genetics with transposons. Transposon mutagenesis. Conjugation (interrupted and non interrupted conjugation, properties of different Hfr strains, zygotic induction, F- x Hfr crosses)
  • Transduction (general, specific and abortive transduction, crosses based on general transduction, characteristics of transducing phages)
  • Transformation
  • Mutations of bacteria (auxotrophic mutants, mutants resistant to antibiotics, nuclear segregation, phenotypic delay, fluctuation test, indirect selection of mutants, mutation rate). DNA repair
  • Restriction and modification of DNA, RM systems of bacteria
  • Molecular evolution of prokaryotic genomes.

Teaching methods
Lectures are based on power-point pictures, tables and texts elaborated according to textbooks, monographs and scientific papers which are explained and complemented with teacher comments. All the presentations are available on IS.
Assessment methods
Visiting of lectures is not obligatory. Oral examination follows the written test in which students should answer 8-10 questions covering main topics of the lecture. During the oral examinations the students have to prove their knowledge on particular examples. To pass the exam they should answer 70% of the questions.
