RESUMO

Fred Sanger was awarded the rare distinction of two Nobel Prizes for Chemistry, in 1958 and 1980. The first was for his work on the structure of proteins, particularly that of insulin, the latter for his contribution concerning the determination of nucleic acid sequences, the foundation work that ultimately led to The Human Genome Project.

RESUMO

A new method for determining nucleotide sequences in DNA is described. It is similar to the "plus and minus" method [Sanger, F. & Coulson, A. R. (1975) J. Mol. Biol. 94, 441-448] but makes use of the 2',3'-dideoxy and arabinonucleoside analogues of the normal deoxynucleoside triphosphates, which act as specific chain-terminating inhibitors of DNA polymerase. The technique has been applied to the DNA of bacteriophage varphiX174 and is more rapid and more accurate than either the plus or the minus method.

RESUMO

A sequence of 50 residues in f1 DNA has been determined by the extension of a chemically synthesized octadeoxyribonucleotide by Escherichia coli DNA polymerase I, with radioactive nucleoside triphosphates and f1 DNA template. The polymerized product was synthesized either in the presence of manganese and a mixture of ribo- and deoxyribotriphosphates or in a magnesium-containing reaction with one or more of the four triphosphates absent. The sequence determination depended largely on fractionation of the polymerized products by two-dimensional "homochromatography." This approach and the techniques for the subsequent sequence analysis should be of general use for determining other sequences of DNA. Several features of this sequence suggest that it is located in an intercistronic region of f1 DNA.
