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 ...

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 ...

The newest DNA sequencing technology from Swiss multinational Roche doesn’t measure DNA directly but in fact analyzes a different polymer altogether. The technology is not yet available for sale, but ...

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 can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...

Researchers at the University of Toronto have invented a new method that uses DNA sequencing to measure metabolites. This enables rapid and precise analysis of biological compounds, such as sugars, ...

DNA methylation is a highly studied epigenetic modification that is involved in regulating genome function and plays fundamental roles in development and disease. 1 It is linked to a broad range of ...
