For decades, biologists have known that the instructions for life are written in DNA, yet the vast majority of those letters seemed to sit in the dark, doing little that was obvious. Now a new ...

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 ...

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 ...

Our DNA is made of millions of combinations of the genomes that create the human body. Even the smallest changes in these sequences, or in how they act, can change the functioning of the whole body ...

A ground-breaking study has traced thousands of conserved regulatory elements back 300 million years, revealing deep principles of plant genome evolution – a discovery that could pave the way for more ...
