Roche has put forward a new approach to genetic analysis, which it describes as sequencing-by-expansion—a proprietary method that pulls apart the DNA molecule and amplifies the signal of each ...

DNA sequencing is a set of laboratory methods for determining the precise linear order of nucleotides (A, C, G, T) in a DNA molecule. Core methodological classes include Sanger sequencing, which uses ...

The presence or absence of remaining foreign DNA from the crossbred progeny of the genome-edited crop and the original crop cultivar can be determined by GenEditScan, based on the k-mer method.

Scientists have taken a major step toward mimicking nature’s tiniest gateways by creating ultra-small pores that rival the dimensions of biological ion channels—just a few atoms wide. The breakthrough ...

A team including researchers at the University of California, Santa Cruz, has received a major grant from the National Human Genome Research Institute (NHGRI) to develop new technology for genome ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

LINE-1 retrotransposons are mobile genome parasites that drive cancer evolution by reshuffling the host genome.

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

If you liked this story, share it with other people. Tyler Kartzinel likens protecting biodiversity to enhancing cellphone networks. His analogy is pretty straightforward: look for gaps in coverage, ...

A hot potato: Next-generation DNA sequencing (NGS) faces mounting scrutiny over its cyber vulnerabilities. While NGS has revolutionized fields ranging from cancer diagnostics to infectious disease ...
