Subject aims: Understanding the basics of contemporary biological science on molecular level, as per medical student's aspiration and future medical practice.
Subject goals: Student has to demonstrate theoretical and practical knowledge of cell structure and function, developmental biology, genetics and basic principles of molecular biology.
Subject components: Basics in molecular biology (DNA structure, replication, transcription and translation), cell biology (cell structure and function, cell organelles, cell signalling, cell-to-cell communication, cell cycle, apoptosys), developmental biology, genetics (fertilization and early embrionic stage, teratogenesis, human genome, principles of inheritance, gene mutations, population genetics, molecular biology of cancer cells, gene therapy ).
Knowledge and skills students have to obtain: microscoping of prepared and wet-mount biological sample slides; cell analysis by fragmentation and centrifugation; plasma membrane analysis: osmosis, plasmolysis, haemolysis, isolation and biochemical analysis; DNA isolation and electrophoresis; performing and understanding molecular biology methods: PCR and RFLP; conducting an information (biology, genetics) search in available internet databases.
Curriculum: All segments of classes (lectures, seminars and practical courses) are interconnected and mandatory for all students to attend. Students are expected to come prepared to class and to actively participate in pre-assigned discussion topic.
Exams: Students will have written exam at the end of the course where minimum of 60% is required for a positive grade.
