DNA is the blueprint of life. Genes encode proteins and serve as the body's basic components. However, building a functioning ...

What scientists once dismissed as junk DNA may actually be some of the most powerful code in our genome. A new international study reveals that ancient viral DNA buried in our genes plays an active ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics-meticulously placed chemical tags that influence which genes are expressed in ...

For decades, scientists have been puzzled by large portions of the human genome labeled as “junk” DNA, sequences that seemingly serve no purpose. Yet, recent studies suggest these cryptic sequences ...

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 ...
