Reconstitution of chemically synthesized ribooligonucleotides with naturally occurring tRNA fragments.
Chemically synthesized yeast tRNA terminal fragments were reconstituted with natural tRNA fragments which were obtained by partial digestion with RNase T1. The synthetic 3'-nonanucleotide (I) accepted alanine (3% with respect to the intact tRNA) when combined with a 4-fold excess of the natural 5'-quarter and the chemically synthesized hexanucleotide (II) stimulated the aminoacylation of the natural 3'-half molecule.
