Nonenymatic ligation of double-helical DNA by alternate-strand triple helix formation.
Nonenzymatic ligation of double-stranded DNA has been performed using an alternate-strand binding oligodeoxyribonucleotide template to juxtapose the duplex termini in a triple helical complex. The template associates with the duplex termini by Hoogsteen hydrogen bonding to alternate strands on opposite sides of the ligation site. Intermolecular and intramolecular ligation of linearized plasmid ...
متن کاملAlternate-strand DNA triple-helix formation using short acridine-linked oligonucleotides.
We have used DNAse I footprinting to examine the formation of intermolecular DNA triple helices at sequences containing adjacent blocks of purines and pyrimidines. The target sites G6T6.A6C6 and T6G6.C6A6 were cloned into longer DNA fragments and used as substrates for DNAse I footprinting, which examined the binding of the acridine (Acr)-linked oligonucleotides Acr-T5G5 and Acr-G5T5 respective...
متن کاملSYNTHESIS AND ANTIMICROBIAL ACTIVITY OF 3-(2’-n-BUTYLBENZOFURAN-3’-YL)-5-ARYL-4, 5-DIHYDRO-1H-PYRAZOLES.
3-(2’-n-butylbenzofuran-3’-yl)-5-aryl-4, 5-dihydro-1H-pyrazoles (4a-4k) have been synthesized. The synthesized products have been assayed for their antimicrobial activity against Gram+ve, Gram-ve bacteria and fungi. All the synthesized products were assigned with IR, 1HNMR, Mass Spectra, TLC, and elemental analysis. Some of the products showed moderate activi...

متن کاملDNA recognition by alternate strand triple helix formation: affinities of oligonucleotides for a site in the human p53 gene.
Duplex DNA recognition by oligonucleotide-directed triple helix formation is generally limited to homopurine target domains. Various approaches have been suggested for the relief of this constraint. Artificial DNA sequences have previously been used to show that adjacent homopurine domains on opposite DNA strands can be simultaneously recognized by oligonucleotide probes that switch triple heli...
