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.
