1. A method for determining a nucleotide sequence for a template nucleic acid by a chain termination sequence method comprising the steps ofa) annealing an oligonucleotide primer to a template DNA molecule,b) adding deoxyadenine-5'"'"'-triphosphate (dATP;
- deoxythymine-5'"'"'-triphosphate (dTTP);
a mixture of deoxyguanine-5'"'"'-triphosphate (dGTP) and deoxyinosine-5'"'"'-triphosphate (dITP), and deoxycytosine-5'"'"'-triphosphate (dCTP), or functional analogs thereof, and chain terminators, and a DNA polymerase, wherein a complementary strand synthesis reaction occurs; and
c) analyzing the results of the complementary strand synthesis reaction so that a nucleotide sequence of the template nucleic acid may be obtained.
