Nanopore sequencing offers rapid, cost-effective DNA analysis, revolutionizing genetic research by identifying nucleotide bases with high throughput and minimal material requirements.
By Sarah MooreJun 10 2024Reviewed by Lexie Corner Nanopore sequencing, developed by Oxford Nanopore Technologies , is a powerful method for rapidly sequencing single ultralong RNA and DNA molecules, aiding in the study of epigenomes, genomes, transcriptomes, and epitranscriptomes.
Nanopore sequencing is a relatively recent addition to NSG technology. It is a fourth-generation method developed and commercialized by ONT.4 This technology involves passing single-strand RNA or DNA molecules through a very small protein channel embedded in an electrically resistant membrane. Charged polymers are electrophoretically translocated through a nanometer-sized aperture or nanopores that are present in a thin membrane. The nanopore is positioned in an electrochemical chamber, separated into cis- and trans-compartments. Each compartment contains conducting buffers.6
Nanopores Used in DNA Sequencing DNA strands pass through nanopores, allowing for the identification of one nucleotide base at a time based on current amplitude, thereby revealing the DNA sequence. This mushroom-like heptameric transmembrane pore consists of a vestibule connected to a transmembrane β-barrel, narrowing to about 1.4 nm at the vestibule.5 This pore is restricted to the translocation of ssDNA . The phi29 system is utilized for the passage of ssDNA, dsDNA, peptides, and small proteins.5

Analysis suggests people with more copies of ribosomal DNA have higher risks of developing diseaseRibosomal DNA (rDNA) is present in hundreds of copies in the genome, but has not previously been part of genetic analyses. A new study of 500,000 individuals indicates that people who have more copies of rDNA are more likely to develop inflammation and diseases during their lifetimes.
