Identifying a target polynucleotide
First Claim
1. A method for identifying the presence of a single-stranded target polynucleotide in a sample, comprising the steps of:
- (I) contacting the target polynucleotide, under hybridising conditions, 5 with at least first and second polynucleotide probes, each of which comprise afirst region complementary to adjacent non-overlapping regions of the target polynucleotide;
(ii) ligating together those first and second polynucleotides that hybridise to the target polynucleotide;
(iii) optionally, amplifying any ligated polynucleotides; and
(iv) determining whether the target polynucleotide is present in the original sample, by detecting any ligated polynucleotide, wherein at least one of the first and second polynucleotides comprise a second region having a defined polynucleotide sequence, with each individual nucleotide of the first region being represented by at least two nucleotides on the second region, and the ligated polynucleotide being identified by determining the second region of at least one of the first and second polynucleotide probes.

Abstract
A method for identifying the presence of a single stranded target polynucleotide in a sample comprising the steps of (i) contacting the target polynucleotide, under hybridising conditions, with at least first and second polynucleotide probes, each of which comprise a first region complementary to adjacent non-overlappïng regions of the target polynucleotide; (ii) ligating together those first and second polynucleotides that hybridise to the target polynucleotide; (iii) optionally, amplifying any ligated polynucleotides; and (iv) determining whether the target polynucleotide is present in the original sample, by detecting any ligated polynucleotide, wherein at least one of the first and second polynucleotides comprise a second region having a defined polynucleotide sequence, with each individual nucleotide of the first region being represented by at least two nucleotides on the second region, and the ligated polynucleotide being identified by determining the second region of at least one of the first and second polynucleotide probes.

17. A method for identifying the order of at least two target sequences on a target polynucleotide, comprising:
-
(i) contacting the target polynucleotide, under hybridising conditions, with at least a first and second polynucleotide probe, each of which comprise a first region complementary to non-adjacent regions of the target polynucleotide; (ii) performing a polymerase reaction to incorporate nucleotides between the at least two probes to thereby form a third polynucleotide; and (iii) determining the order of, and distance between, the two target sequences on the target polynucleotide, by detecting any third polynucleotide, wherein the first and second polynucleotides comprise a second region having a defined polynucleotide sequence, with each individual nucleotide of the first region being represented by at least two nucleotides on the second region, and the order of and distance between the probes in the third polynucleotide being identified by detecting the second region of the first and second polynucleotide probes.
