Abstract
Self-assembly properties and diversity in higher-order structures of DNA enable programmable tools to be used to construct algorithms at the molecular level. However, the utility of DNA-based programmable tools is hampered by the low orthogonality to natural nucleic acids, especially in complex molecular systems. To address this challenge, we report here the orthogonal regulation of DNA self-assembly by using an unnatural base pair (UBP) formation. Our newly designed UBP AnN:SyN is formed in combination with anti and unusual syn glycosidic conformation with high thermal stability and selectivity. Furthermore, AnC worked as a pH-sensitive artificial nucleobase, which forms a strong base pair with cytosine under a weak acidic condition (pH 6.0). The orthogonal AnN:SyN base pair functioned as a trigger for hybridization chain reaction to provide long nicked double-stranded DNA (ca. 1000 base pairs). This work represents the first example of the orthogonal DNA self-assembly that is nonreactive to natural four-letter alphabets DNA trigger and expands the types of programmable tools that work in a complex environment.

Abstract
Oligonucleotides are biopolymers that can be easily modified at various locations. Thereby, the attachment of metal complexes to nucleic acid derivatives has emerged as a common pathway to improve the understanding of biological processes or to steer oligonucleotides towards novel applications such as electron transfer or the construction of nanomaterials. Among the different metal complexes coupled to oligonucleotides, ruthenium complexes, have been extensively studied due to their remarkable properties. The resulting DNA-ruthenium bioconjugates have already demonstrated their potency in numerous applications. Consequently, this review focuses on the recent synthetic methods developed for the preparation of ruthenium complexes covalently linked to oligonucleotides. In addition, the usefulness of such conjugates will be highlighted and their applications from nanotechnologies to therapeutic purposes will be discussed.

Abstract
The present work reports on the preparation of oligonucleotide conjugates via the formation of aromatic oxime linkage. The conjugation consists in the reaction between the oligonucleotide derivatized at 5'-extremity with a benzaldehyde moiety and an aminooxy reporter group. The conjugation was found highly efficient and was extended for the conjugation of phosphorothioate oligonucleotide. In addition, the stability of the so-formed oxime conjugate was investigated.

Abstract
Oligodeoxyribonucleotide multiphosphonate conjugates have been prepared by on-support oximation of aminooxy-functionalized oligonucleotides with 2-(4-formylphenoxy)ethyl esters of nitrilotris(methylenephosphonic acid) (NTP) and ethylenediaminetetrakis(methylenephosphonic acid) (EDTP). These conjugates, along with the corresponding oligonucleotides bearing hydroxy or monophosphate termini, were hybridized with a longer substrate DNA leaving a narrow single-stranded gap site in the substrate between the two additive oligonucleotides. Gap sites flanked by two of the multiphosphonate groups, in particular EDTP, were hydrolyzed by the Ce(IV)-EDTA complex significantly faster than the corresponding gap sites flanked by only hydroxy or monophosphate termini. Using the new oligonucleotide conjugates, efficient site-selective hydrolysis of the substrate DNA can be achieved at Ce(IV) concentrations where other single-stranded regions remain intact. At high Ce(IV) concentrations, the cleavage rate becomes independent on [Ce(IV)] and little improvement by the new multiphosphonate conjugates over oligonucleotides with monophosphate termini is observed, suggesting that the origin of the rate acceleration is the higher affinity of the NTP or EDTP ligands to Ce(IV) compared to hydroxy or monophosphate ligands.

Abstract
A novel solid support 1 was synthesized to incorporate glyoxylic aldehyde functionality at the oligonucleotide 3'-terminus. 6-mer and 11-mer oligonucleotide sequences containing 3'-glyoxylic aldehyde functionality were prepared by using this support. These modified oligonucleotides were coupled to reporters containing an aminooxy group to prepare oligonucleotide 3'-conjugates through glyoxylic oxime bond formation. The hydrolytic stability of a glyoxylic oxime linkage was also investigated. [reaction: see text].

Abstract
The incorporation of fluorescently labeled nucleotides into DNA by DNA polymerases has been used extensively for tagging genes and for labeling DNA. However, we lack studies comparing polymerase efficiencies for incorporating different fluorescently labeled nucleotides. We analyzed the incorporation of fluorescent deoxynucleoside triphosphates by 10 different DNA polymerases, representing a cross-section of DNA polymerases from families A, B, and reverse transcriptase. The substitution of one or more different reporter-labeled nucleotides for the cognate nucleotides was initially investigated by using an in vitro polymerase extension filter-binding assay with natural DNA as a template. Further analysis on longer DNA fragments containing one or more nucleotide analogs was performed using a newly developed extension cut assay. The results indicate that incorporation of fluorescent nucleotides is dependent on the DNA polymerase, fluorophore, linker between the nucleotide and the fluorophore, and position for attachment of the linker and the cognate nucleotide. Of the polymerases tested, Taq and Vent exo DNA polymerases were most efficient at incorporating a variety of fluorescently labeled nucleotides. This study suggests that it should be feasible to copy DNA with reactions mixtures that contain all four fluorescently labeled nucleotides allowing for high-density labeling of DNA.

Abstract
A convergent strategy for the synthesis of peptide-oligonucleotide conjugates (POC) is presented. Chemoselective ligation of peptide to oligonucleotide was accomplished by oxime and thiazolidine formation. Oxime conjugation was performed by treating an oxyamine-containing peptide with an aldehyde-containing oligonucleotide or vice versa. Ligation by thiazolidine formation was achieved by coupling a peptide, acylated with a cysteine residue, to an oligonucleotide that was derivatised by an aldehyde function. For both approaches, the conjugates were obtained in good yield without the need for a protection strategy and under mild aqueous conditions. Moreover, the oxime ligation proved useful for directly conjugating duplex oligonucleotides. Combined with molecular biology tools, this methodology opens up new prospects for post-functionalisation of high-molecular-weight DNA structures.

Abstract
We describe the preparation of oligonucleotides containing a 5'-linker bearing an aminooxy group. Use of the trityl protecting group for the aminooxy moiety allows purification of the modified oligonucleotide by reverse phase HPLC and cleavage in mild acidic conditions. Derivatization with an aldehydic reporter group is efficient and rapid.
