The invention relates to methods for pairwise sequencing of a polynucleotide template which result in the sequential determination of nucleotide sequence in two distinct and separate regions of the polynucleotide template.

One or more nanoparticles, each of which is conjugated with at least one oligonucleotide, are used to multiply nucleic acids. One or more of the oligonucleotides has at least one primer sequence and an additional segment extending from the end of the primer sequence proximal to the nanoparticle in the direction of the nanoparticle, and the additional segment has at least one abasic modification. The disclosed method for multiplying nucleic acids has a multiplication step and a test step for determining the concentration of the products of the multiplication reaction. The test step begins after the multiplication step ends, and in the test step, either at least one part of the sample is supplied with substances or no substances are supplied. In a method for multiplying nucleic acids, nanoparticles transfer heat into their surroundings in a reaction volume upon being excited. A method for multiplying a nucleic acid has an amplification step that uses a polymerase chain reaction, where a cycle consisting of the steps of denaturing, annealing, and elongating is repeated.

The present invention relates to the detection of a target nucleic acid sequence by a PTOCE (PTO Cleavage and Extension) assay. The present invention detects a target nucleic acid sequence in which the PTO (Probing and Tagging Oligonucleotide) hybridized with the target nucleic acid sequence is cleaved to release a fragment and the fragment is hybridized with the CTO (Capturing and Templating Oligonucleotide) to form an extended duplex, followed by detecting the presence of the extended duplex. The extended duplex provides signals (generation, increase, extinguishment or decrease of signals) from labels indicating the presence of the extended duplex and has adjustable T.sub.m value, which are well adoptable for detection of the presence of the target nucleic acid sequence.

The present invention relates to the detection of a target nucleic acid sequence by a PTOCE-E (PTO Cleavage and Extension-dependent Extension) assay. The PTOCE-E assay of the present invention can reduce the non-target signal and increase the target signal as compared with the conventional PTOCE and PCE-SH methods, thereby enabling more accurate detection of the target nucleic acid sequence.
