The course did not only comprise theoretical lectures, but really hands-on experience. We went out to different spots in Drøbak […]

The mitochondrial gene order of Annelida – extremely old, but still working

Mitochondria are the energy plant of our cells. Originally, they were bacteria, but then they were captured by the ancestors of eukaryotes (among others all animals, mushrooms and plants) and used to produce energy for the cell. This is also known as the endosymbiotic theory. An inheritance from […]
