May 09, 2014 Figure 1: Quantitative base-induced DNA cleavage (QBIC) is a technique that allows DNA to be cleaved at any thymine site. Credit: lvcandy/iStock/Thinkstock Genetic engineering of plants, animals and microorganisms such as bacteria typically involves the use of restriction enzymes to 'cut and paste' DNA fragments into certain genetic sequence locations. This process allows scientists to introduce new genes into an organism, but is constrained to specific recognition sequences, limiting the design of recombinant DNA molecules. A research team led by Hiroki Ueda and colleagues from the Laboratory for Synthetic Biology at the RIKEN Quantitative Biology Center has now developed a chemical-based, non-enzymatic recombination technique that instead uses a DNA base analogue called 5-ethynyluracil to cleave DNA at any site containing the nucleotide thymine. The technique developed by Ueda and his co-workers, which is called quantitative base-induced DNA cleavage (QBIC), starts with the generation of DNA fragments containing 5-ethynyluracil in place of thyminetwo molecules with similar structures. These products are then immersed in an aqueous solution containing methylamine, a derivative of ammonia. In this chemical bath, all the nucleotides containing 5-ethynyluracil become cleaved, introducing gaps near the cleaved ends. The gaps in the resulting DNA fragments create protruding … Continue reading →
