Microbial (bacterial) genetics

Genetic information is stored in all cells in the form of a DNA, nucleic acid molecule. A segment of DNA that codes for a molecule with a specific function is a gene. It represents the basic unit of genetic information. In bacteria, DNA is most often found in the form of one chromosome and several smaller plasmids.

Bacteria are characterized by horizontal gene transfer, for which three processes are responsible: conjugation, transduction, transformation. These processes allows bacteria to acquire new genes and thus new properties, e.g. resistance to antimicrobial agents. The lecture includes basic concepts of genetics, genetics of bacteria, explains the processes of gene expression and horizontal transfer of genes between bacteria. It explains what genetic engineering is and what it means for human medicine.
