Abstract: Techniques for random access of particular DNA strands from a mixture of DNA strands are described. DNA strands that encode pieces of the same digital file are labeled with the same identification sequence. The identification sequence is used to selectively separate DNA strands that contain portions of the same digital file from other DNA strands. A DNA staple positions DNA strands with the identification sequence adjacent to sequencing adaptors. DNA ligase joins the molecules to create a longer molecule with the region encoding the digital file flanked by sequencing adaptors. DNA strands that include sequencing adaptors are sequenced and the sequence data is available for further analysis. DNA strands without the identification sequence are not joined to sequencing adaptors, and thus, are not sequenced. As a result, the sequencing data produced by the DNA sequencer comes from those DNA strands that included the identification sequence.

Abstract: One or more enzymes are used to repair damage in synthetic DNA molecules that encode digital information. The enzymes are included in a repair mixture containing one or more of DNA polymerase, DNA ligase, T4 Endonuclease, Endonuclease IV, Endonuclease VIII, and uracil glycosylase. The repair mixture may also contain one or more of a buffering solution, oxidized nicotinamide adenine dinucleotide (NAD+), and deoxyribose nucleoside triphosphates (dNTPs). The synthetic DNA molecules are incubated with the repair mixture for approximately four hours. Use of the repair solution allows recovery of the digital information from damaged DNA molecules.

Abstract: Means and methods for preparing double stranded target DNA molecules for sequencing. In embodiments double stranded backbone DNA molecules comprising 5? and 3? ends are provided that are: ligation compatible with 5? and 3? ends of the target DNA; form a first restriction enzyme recognition site when self-ligated; in a form that enables self-ligation. Methods may comprise providing, if not already present, the target DNA with 5? and 3? ends that are in a form that prevents self-ligation and that are ligation compatible with the backbone DNA 5? and 3? ends. Methods may further comprise ligating the target DNA to the backbone DNA in the presence of a ligase and a first restriction enzyme that cuts the first restriction enzyme recognition site, thereby producing at least one DNA circle comprising a backbone DNA molecule and a target DNA molecule.

Abstract: The subject invention pertains to the rapid amplification and real-time monitoring of nucleic acid sequences at a constant temperature. Specifically, fluorescent or electroactive-labeled loop probes and primers are designed to be specific to identified regions of a target nucleic acid sequences and subsequently amplify and permit the identification of the presence of the target sequence. In this method, a DNA polymerase with no 5? to 3? exonuclease activity is added to extend the primers and probes, while a nicking endonuclease is added to specifically identify the amplified nucleic acid product and cleave the label from the loop probe-extended DNA duplex.

Abstract: Molecules may be analyzed (e.g., sequencing of nucleic acid molecules) by tunneling recognition at a tunneling junction. Embodiments of the present invention may allow detecting individual nucleotides and the sequencing of a nucleic acid molecule using a tunneling junction. By labeling a specific nucleotide with a moiety, tunneling junctions may generate a signal with a suitable signal-to-noise ratio. The tunneling recognition uses a tunneling current that is mostly through the moiety rather than mostly through the nucleotide or a portion of the molecule of interest. Because a single nucleotide can be detected with a signal with a suitable signal-to-noise ratio resulting from the tunneling current passing through the moiety, embodiments of the present invention may allow for fast detection of nucleotides using a tunneling current.

Abstract: Disclosed are methods and systems for detecting RNA and sequencing RNA in a wide range of samples such as samples with low concentrations of nucleic acid, samples with degraded nucleic acid, samples that would not otherwise be amenable to conventional sequencing or RNA detection methods, poor quality samples, high quality samples in which rare mutations are sought, formalin-fixed paraffin-embedded samples, blood samples, etc. The methods of the present invention may use paired, large panels of primers to amplify many short fragments that overlap between but not within each panel. Each panel's amplicon set may fill the gaps between those of the opposing panel, thereby providing complete gene or genomic coverage. A preliminary, multiplex amplification step amplifies target nucleic acid for all downstream reactions such as Sanger sequencing, cloning, and Next Generation Sequencing (NGS).
