DNA, which contains the genetic information of an organism, consists of long chains of nucleotides. In order to study the functions based on the sequence of these building blocks, DNA molecules must be inserted in carrier molecules (plasmid-vectors) to be multiplied. For this cloning process, a research team from the University of Bayreuth has developed a highly efficient, fast and inexpensive method that is versatile enough to be deployed in all areas of biology, biochemistry and biotechnology. A key feature of the method is that it makes any painstaking screening of bacterial colonies unnecessary. The scientists presented their innovation in the journal Scientific Reports.
