Abstract

Trinucleotide phosphoramidites representing codons for all 20 amino acids have been prepared and used in automated, solid-phase DNA synthesis. In contrast to an earlier report, we show that these substances can be used to introduce entire codons into oligonucleotides in excess of 98% yield, and are ideal reagents for the synthesis of mixed oligonucleotides for random mutagenesis.
