Completely updated in line with the rapid progress made in the field, this new edition of the highly-praised textbook addresses powerful new methods and concepts in biotechnology, such as genome editing, reprogrammed stem cells, and personalized medicine. Later, bioinformatics tools were developed to identify three kinds of DNA modifications (6mA, 5mC and 5hmC) from ONT data71,75. The DNA extraction and purification methods used in these independent studies are summarized in Supplementary Table 1. Identification and characterization of occult human-specific LINE-1 insertions using long-read sequencing technology. In parallel, accuracy has been improved through new base-calling algorithms, including many developed through independent research32,44 (see below). For small DNA/RNA viral genomes (for example, the 27-kb human coronavirus genome86), the assembly process is not required given the long read length.

The expected data output of a flow cell mainly depends on (1) the number of active nanopores, (2) DNA/RNA translocation speed through the nanopore and (3) running time. Compared to existing antibody-based approaches (which are usually followed by short-read sequencing), ONT direct RNA sequencing opens opportunities to directly identify RNA modifications (for example, m6A) and RNA editing (for example, inosine), which have critical biological functions.

Compared to PacBio, ONT performs better in detecting 5mC but has lower accuracy in detecting 6mA68,75,81. The former strategy requires less sample manipulation and is quicker and thus is good for on-site applications, whereas the latter produces a more stable library for longer sequencing courses and therefore produces higher yields. The long-read length is well suited to identifying large-range genomic complexity with unambiguous alignments, whereas the high accuracy and high throughput of short reads is useful for characterizing local details (for example, splice site detection with single-nucleotide resolution) and improving quantitative analyses.

They both construct a fusion protein of the adenosine methyltransferase and protein A to convert specific proteinDNA interactions to an artificial 6mA profile, which is subsequently detected by ONT sequencing. Both types of sequencing have their own benefits and drawbacks, depending on the specific goals of the experiment.
