\b[J. Michael Li] is a coauthor, with <Xueguang Sun> and <Roger M. Wartell>, of the2007 study of frozen-solution conversion between an <RNA hairpin> and a metastable <RNA dimer>. The paper identifies the authors with Georgia Tech's School of Biology and gives Li's byline in this form.<Conversion of stable RNA hairpin to a metastable dimer in frozen solution by Xueguang Sun and others>[Title-page byline and affiliation]{ref}
The study examined a79-nucleotide <RNA> with two bands in native <gel electrophoresis> but one in denaturing conditions. <Sedimentation equilibrium> supported monomer and dimer assignments. Experiments on shorter segments implicated the first21nucleotides in dimer formation.<Conversion of stable RNA hairpin to a metastable dimer in frozen solution by Xueguang Sun and others>[Abstract and Results, monomer/dimer identification and21-nucleotide segment]{ref}
A useful distinction follows: two native gel bands alone do not count the number of strands in each structure. Changing the folding state can change <electrophoretic mobility> without changing strand mass. Combining a mobility observation with an independent association measurement addresses that ambiguity, which is central to interpreting this contribution.
