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 ...

Mutations are changes in the molecular 'letters' that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

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 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 ...

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint ...
