摘要：

Poly(A)-containing RNA was isolated by oligo(dT)-cellulose chromatography from maize embryos incubated in the presence of 32PO4. Complete ribonuclease digests of the isolated RNA were fractionated by two-dimensional electrophoresis. Besides the 4 major nucleotide constituents, 5′-terminal 'cap-structures' and N6-methyladenylic acid were detected on the electrophoretograms. There were approx. two residues of N6-methyladenylic acid per 1600 nucleotide residues. © 1979.
