17 September 2020 / A new publication shows that experiments using new genetic engineering techniques were conducted in Germany on cattle. Using a newer version of the so-called CRISPR/Cas gene scissors, the aim of the experiments was to produce hornless dairy cows. To achieve this, cells were taken from the skin of a breeding bull. These cells were subsequently genetically engineered. Afterwards, in an approach similar to that used in cloning ‘Dolly the sheep’, the nuclei from the cells were transferred into ova (egg cells).
