Pulsed field-gradient NMR experiments can be used to measure the diffusion constants of nucleic acids. The diffusion constants measured in this way for double-helical DNAs of defined length agree well both with theory and with measurements done using other techniques. When applied to RNAs, this experiment easily distinguishes duplex RNAs from RNA hairpins(More)
Learners benefit from creating personally meaningful artifacts for an audience, especially when those artifacts embody the concepts that the learners aim to understand. Our past work examined artistic design as an anchor for mathematical discussions between learners as they explored concepts like symmetry and fractions. In this paper, we present the work(More)
