Switching DNA and RNA on and off

DNA and RNA are naturally polarized molecules. Scientists believe that these molecules have an in-built polarity that can be reoriented or reversed fully or in part under an electric field. In a new study scientists show that all the DNA and RNA building blocks, or nucleobases, exhibit a non-zero polarization in the presence of polar atoms or molecules such as amidogen and carbonyl.
