title: Total synthesis of the structural gene for the precursor of a tyrosine suppressor transfer RNA from Escherichia coli. 3. Synthesis of deoxyribopolynucleotide segments corresponding to the nucleotide sequence 27-51.
abstract: Chemical syntheses of the four deoxyribodecanucleotides, d(T-C-G-A-A-G-T-C-G-A), d(C-G-T-C-A-T-C-G-A-C), d(T-G-A-C-G-G-C-A-G-A), and d(C-T-A-A-A-T-C-T-G-C) are described. These polynucleotides form, respectively, segments 7 to 10 in the plan adopted for the total synthesis of the DNA corresponding to the precursor for the Escherichia coli tyrosine tRNA. The syntheses used the principles of stepwise addition of protected mono- and oligonucleotides to the 3'-hydroxyl end of growing oligonucleotide chains. Detailed schemes used in the present syntheses are shown in Diagrams 1 to 4 in the text. The final products were subjected to extensive chromatography and were characterized as pure by chemical and enzymatic procedures.
