Biochemists Switch DNA Functions on and Off Using Light

Posted by in categories: bioengineering, biotech/medical, chemistry, genetics

Biochemists use protein engineering to transfer photocaging groups to DNA.

DNA (deoxyribonucleic acid) is the basis of life on earth. The function of DNA is to store all the genetic information, which an organism needs to develop, function and reproduce. It is essentially a biological instruction manual found in every cell.

Biochemists at the University of Münster have now developed a strategy for controlling the biological functions of DNA with the aid of light. This enables researchers to better understand and control the different processes which take place in the cell – for example epigenetics, the key chemical change and regulatory lever in DNA.
