Module aim (aims)

The lecture is addressed to students who want to gain or extend their knowledge about the most important and aspects of biotechnology. The lecture will begin with recollecting of basic information concerning the structure of deoxyribonucleic acid (DNA). Then it will continue to show how the DNA became a hearth of technology that is transforming many fields of our life such as pharmacy, agriculture and criminology.During the lecture the following questions, among many others, will be answered: How bacteria can produce human insulin? What makes a triple helix useful in drug design? Why identical twins are not identical? What is the Human Genome Project? Why HIV defies the central dogma governing the flow of genetic information? What is cloning and PCR? Does DNA recombination occur in the nature? What is “a gene gun”? What can be advantages of transgenic plants?
1. Module aim (aims)The main objectives of the lectures are to introduce students to the fieldof biotechnology and genetic engineering. Students will be provided with the following knowledge:
· Structure and significance of DNA and RNA.
· Methods of DNA isolation, purification and detection.
· Enzymes acting on the nucleic acids.
· Recombinant DNA, principles of gene cloning.
· Genetic engineering in pharmaceutical industry and in agriculture.
· Polymerase chain reaction and methods for DNA sequencing

Pre-requisites in terms of knowledge, skills and social competences (where relevant)

Knowledge of biochemistry (on very basic level)

Syllabus

Week 1: Structure and significance of DNA. Discovery of the DNA structure, primary and secondary DNA structure, types of base pairing, conformations of double helix, transfer of information in the cell.
Week 2: Isolation and purification of DNA. Enzymes acting on nucleic acids. Techniques for isolation of DNA from cells (methods for cell’s opening, ion-exchange chromatography). Techniques for separation and visualisation of DNA (gel electrophoresis, autoradiography, luminescence, fluorescence). Polymerases, nucleases and ligases as enzymes acting on nucleic acids, examples of restriction endonucleases.
Week 3: Genes and cloning. Natural clones, methods for laboratory cloning: artificial embryo twinning, somatic cell nuclear transfer, cloning vectors, bacteriophages.
Week 4: Genetic engineering. Basic terms for genetic engineering. Polymerase Chain Reaction (PCR), reverse transcriptase, retroviruses (HIV), expression vectors, bacteria as “protein factories.
Week 5: Genetic engineering in agriculture. Methods for DNA sequencing. Applications of genetic engineering, “natural” engineering, genetically modified organisms, methods for insertion of foreign genes into a plant cells. Methods for DNA sequencing: Sanger-Coulson method, method of chemical degradation, pirosequencing.
Week 6: Discussion and preparation for visit to laboratory of molecular biology.
Week 7: Visit to laboratory of molecular biology. Subject of the visit: “Digesting of plasmid DNA by the use of restriction endonucleases”; presentation of the laboratory, preparation of reaction, digesting with restriction enzymes, electrophoresis, visualization of the products, discussion.
