Divalent metal ions have profound effects on the conformation of poly 9, as indicated by changes in optical rotatory dispersion and ultraviolet spectra, with different metal ions having distinctly different effects. At pH 6 and in the presence of 5 X 10-3&f NaCl, two moles Ni(I1) or Co(I1) per mole

The polyrihonucleotides of adenylic, cytidylic, and uridylic acids are degraded in a 2-hr. period at 64ยฐC. into low molecular weight oligoniicleot,ides and mononncleotides through the action of lanthanum ( 111) or other trivalent inner transition met,al ions. Polyinosinic arid is degraded somewhat m

Polyadenylic acid is degraded into niononncleotides and low molecular might, oligoniicleotides in a 20 hr. period at 64ยฐC. by the action of ;\In (II), Co (11), Xi (11), and Cri (11) ions, and in a 2 hr. period by Zn (11) ions. The latter also degrade poly C, poly U, and RNA at approsimately the same
