The (R)-2-(adenin-9-yl)propanoic acid 2 was prepared from adenine and (S)-ethyl lactate by using the triphenyl phosphine-diethyl azodicarboxylate system. The (R)-2-(thymin-l-yl)propanoic acid, (R)-2-(cytosin-l-yl)propanoic acid, and (R)-2-(hypoxanthin-9-yl)propanoic acid were also prepared.
## Abstract Two electrophoretic components have been detected on the ascending boundary in unbuffered solutions of polyglutamic acid and polylysine under certain experimental conditions. If the conditions are favorable to aggregation, another maximum, the third in order, is formed on this boundary.
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 +
