A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

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

A pair of papers published this week in the two leading scientific journals mark the completion of the Human Genome Project and the start of a new project to find all of the functional elements in ...

Since its development in the late 1970s, DNA sequencing has become one of the most influential tools in biomedical research, with technologies evolving continuously and new applications emerging over ...

Fragments of DNA from long-extinct human relatives still circulate in modern genomes, and in some cases they do more than ...

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 ...

Researchers have used a new human reference genome, which includes many duplicated and repeat sequences left out of the original human genome draft, to identify genes that make the human brain ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...

Scientists have decoded the world’s oldest human DNA sequence, beating the previous record by almost 300,000 years, and at the same time confusing what we know of our early relatives. Published in ...
