Every year on the Day of Prayer and Repentance, THI invites schoolgirls from the 9th grade onwards to the Technology Day. Here, the schoolgirls can obtain information about the various study programs, get to know everyday life at university and gather impressions in the laboratories.

Dr. Kathrin Tissot-Daguette, Professor of Biotechnology and Management, is a lecturer on the Life Science Management (LSM) program at THI Business School and came up with something special for her groups of schoolgirls: using simple household items, the DNA of strawberries was isolated and thus made visible. The students eagerly got down to work and mixed solutions, mashed the strawberries and filtered the resulting mixture. After adding alcohol at the end, the DNA slowly became visible and could be skimmed off.

Later, Prof. Tissot-Daguette gave more detailed explanations about DNA and an overview of the current state of research. The students were very interested and asked many questions.
