What happens in a cell when genetic information is translated into proteins? In order to study this process, researchers study one particular biomolecule inside the cell: messenger ribonucleic acid, mRNA for short. This biomolecule plays a major role in all cellular processes—and it is also the focus of joint research being carried out by two groups at the Cells-in-Motion Cluster of Excellence at Münster University. One of the groups consists of biochemists and is headed by Prof. Andrea Rentmeister; the other is made up of molecular biologists and is led by Dr. Sebastian Leidel.
