Abstract

With the ultimate objective of the total synthesis of a tRNA gene including its transcriptional signals, an Escherichia coli tyrosine suppressor tRNA gene was chosen. The arguments in favor of this choice are presented. A plan for the total synthesis of the 126-nucleotide-long DNA duplex corresponding to a precursor (Altman S., and Smith, J. D. (1971) Nature New Biol. 233, 35) to the above tRNA is formulated. The plan involves: (a) the chemical synthesis of 26 deoxyribooligonucleotide segments, (b) polynucleotide ligase-catalyzed joining of several segments at a time to form a total of four DNA duplexes with appropriate comlementary single-stranded ends, and (c) the joining of the duplexes to form the entire DNA duplex. Ten accompanying papers describe the experimental realization of this objective.
