## Abstract MS2 RNA, which sediments at 27S in a neutral buffer, can be converted to a compact 57S conformation at pH 3.8. Requirements for this conversion, besides protonation, are small concentrations of Mg^++^ ions and a low ionic strength. On the other hand, after heating in the presence of EDT
## Abstract The molecular weight of native 26.6S MS2 RNA, of acidic 53.1S MS2 RNA and of formaldehydeβtreated 36.1S MS2 RNA was determined by lightβscattering studies. The three forms examined correspond to monomers. Also Ξ½v values were determined, and in conjunction with our previous estimates for
