Rabbit liver tRNA nucleotidyltransferase was used to synthesize modified tRNA molecules containing an additional CMP residue at the 3′ terminus. In the first step tRNA-C-C was converted to tRNA-C-C-C by a minor activity of the purified enzyme. In the second step the lengthened molecules were converted to tRNA-C-C-C-A. AMP addition to tRNA-C-C-C occurred at about 50% the rate with tRNA-C-C. Aminoacylation studies indicated that tRNA-C-C-C-A was active for acceptance of at least 12 amino acids.
