The lecture covers the wide area of the yeast biology: yeast cytology, regulation of the cell cycle,aging, apoptosis, mating, meiosis and sporulation, killer phenomenon, nuclear and mitochondrial genome, prions, transposons, yeast metabolism , taxonomy, yeast as pathogens, yeasts in industry, ecology of yeasts. The emphasis is laid on recent progress in understanding of the yeast genetics and molecular biology.

It is recommended to enroll on a practical course (Practical course in molecular and cell biology of the yeasts - MB140C29).
It is recommend previous completion of the lecture Essentials in molecular biology and Microbiology.

Requirements to the exam
Last update: RNDr. Michaela Schierová, Ph.D. (24.10.2019)

Exam requirements - knowledge of the content of lectures. The exam is written, containing 3 questions where a more extensive answer is expected - each question is rated max. 8 points and 10 questions where only a very brief answer is required - here a maximum of 2 points can be obtained for each answer. It's 1 hour to work out the answers. If interested, an oral exam can be arranged.
