Comparative base compositions of chloroplast and cytoplasmic tRNA Phe 's from Eugiena gracilis

Abstract

The nucleoside compositions of chloroplast and cytoplasmic tRNAPhe's from Euglena gracilis have been determined. The modified nucleoside compositions of these two tRNAs indicate that tRNAPheChl is more similar to procaryotic (E. coli) tRNAPhe than to either the Euglena cytoplasmic tRNAPhe or other eucaryotic cytoplasmic tRNAPhe's.
