Rat liver cytoplasmic tRNA population was separated by h.p.l.c. using
a gradient of acetonitrile/ammonium acetate. Chromatographic data for
separation of the asparagine, leucine, and serine isoacceptor species
are reported. concentrations of these tRNA species, area peak percenta
ges, were analyzed and compared to theoretical data for the fractional
use of each codon for aminoacid.
