Abstract

The present invention relates to a method for preparing a library of template polynucleotides and use thereof in methods of solid-phase nucleic acid amplification. More specifically, the invention relates to a method for preparing a library of template polynucleotides that have common sequences at their 5′ ends and at their 3′ ends.

Claims

1. A forked polynucleotide adapter formed by annealing of partially complementary first and second polynucleotide strands, wherein at least one of the strands comprises a polynucleotide sequence complementary to the sequence of SEQ ID NO:

4.

2. The adapter of claim 1, wherein a sequence of at least 20 consecutive nucleotides at the 5′

end of the first strand and a sequence of at least 20 consecutive nucleotides at the 3′

end of the second strand are not complementary to each other, such that a mismatched region of at least 20 consecutive nucleotides on each strand remains in single stranded form when first and second strands are annealed.

3. The adapter of claim 1, wherein one of the first and second polynucleotide strands comprises the sequence of SEQ ID NO:

2.

4. A library of nucleic acids comprising a plurality of different polynucleotide duplexes having identical forked polynucleotide adapters at each end, wherein the adapters are formed by annealing of partially complementary first and second polynucleotide strands, and at least one of the strands comprises a polynucleotide sequence complementary to the sequence of SEQ ID NO:

4.

5. The library of claim 4, wherein a sequence of at least 20 consecutive nucleotides at the 5′

end of the first strand of the adapters and a sequence of at least 20 consecutive nucleotides at the 3′

end of the second strand of the adapters are not complementary to each other, such that a mismatched region of at least 20 consecutive nucleotides on each strand remains in single stranded form when the first and second strands are annealed.

6. The library of claim 4, wherein one of the first and second polynucleotide strands comprises the sequence of SEQ ID NO:

2.

7. The library of claim 4, wherein the library comprises sequences of a whole complex polynucleotide sample.

8. The library of claim 4, wherein the plurality of different polynucleotide duplexes are fragments of genomic DNA.
