Interaction of poly(X) with poly(U) to form a regular, ordered structure has been investigated by uv, CD, and ir spectroscopy. The XU complex exhibits a marked dependence of T, on the nature of the alkali metal ion present in solution. Stability of the complex is surprisingly high and increases with

It is demonstrated that poly(A + U) and poly(1 + C) are both formed nnder low ionic strength conditions. Continuous variation studies indicate the formation of copper(I1) complexes of poly A, poly C, and poly I, but not of poly U. Copper(I1) in a I: 1 ratio to polynucleotide prevents the formation o
The optical density-temperature profile of double-stranded poly(A + U), triplestranded poly(A + 2U), and double-stranded RNA from rice dwarf virus in solutions with and without poly-clysine has been examined. When poly-clysine is added, more than one melting temperature T , is observed for poly(A +
## Abstract The interaction of silver ions with poly(A) was studied by potentiometric titration, uv spectrophotometry, and stoppedβflow spectroscopy. For 0 < __r__~__b__~ < 0.5, where __r__~__b__~ is moles of silver ion bound per mole of nucleotide base, there exists only one type of binding for po
