摘要： The invention relates to the sequencing of a target polynucleotide sequence, immobilized on a solid support, using the polymerase reaction to extend a suitable primer and characterizing the sequential addition of labelled bases. The present invention further relates to the presence of a polymerase enzyme that retains a 3′ to 5′ exonuclease function, which is induced to remove an incorporated labelled base after detection of incorporation. A corresponding non-labelled base may then be incorporated into the complementary strand to allow further sequence determinations to be made. Repeating the procedure allows the sequence of the complement to be identified, and thereby the target sequence.
