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 ...

In a single experiment, scientists can decipher the entire genomes of many patient samples, animal models or cultured cells. To fully realize the potential to study biology at this unprecedented scale ...

Definition: DNA amplification is the laboratory process of making many copies of a selected DNA sequence from a very small starting amount. It allows DNA that would otherwise be too scarce to detect ...
