'Junk' DNA Cut-and-paste Protein: Discovery May Prove Invaluable In Quest For Gene Therapies

Scientists have identified how a protein enables sections of so-called junk DNA to be cut and pasted within genetic code -- a finding which could speed development of gene therapies. The study sheds light on the process, known as DNA transposition, in which shifted genes have a significant effect on the behavior of neighboring genes. In the human genome, rearrangement of antibody genes can enable the immune system to target infection more effectively.
