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 ...

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 ...

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 ...
