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 ...

Saliva can provide researchers with a source of high-quality human genomic DNA. Although blood is commonly employed for this purpose, saliva offers several advantages. It is more readily accessible, ...

Scientists have uncovered an enormous hidden archive of plant DNA that has endured for more than 400 million years. By comparing hundreds of plant genomes, researchers identified more than 2.3 million ...

Scientists have developed a new technique that could change how we design DNA for therapeutic and biotech applications. The challenge in synthetic biology has always been this: scientists can program ...

DNA is the blueprint of life. Genes encode proteins and serve as the body's basic components. However, building a functioning organism also requires precise instructions about when, where, and how ...
