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 ...

This image compares three DNA sequencing technologies: Sanger sequencing, Massively Parallel DNA sequencing, and Nanopore DNA sequencing. Sanger sequencing (left) sequences 500-700 bases per reaction ...

This image illustrates the typical steps in next-generation sequencing (excluding single-molecule sequencing methods). The process begins with isolating genomic DNA (a) and breaking it into short ...

The first DNA sequencing was performed by Sanger and co-workers in the 1970s, using a method based on the attenuation of the growing nucleotide chain with dideoxythymidine triphosphate (ddTTP). The ...

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 ...

DNA methylation is a highly studied epigenetic modification that regulates genome function and plays key roles in development and disease 1. It is linked to a broad range of conditions, including ...
