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 ...

Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...

Researchers at The University of Texas MD Anderson Cancer Center have identified a key enzyme—RNase H2—that helps ...

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 ...

Inhibiting RNase H2 increases DNA damage and activates immune responses in triple-negative breast cancer, suggesting a ...

Shixin Liu is pioneering new ways of studying the tiny proteins that copy and read DNA in living cells. (Credit: Roshni Khatri) Inside every cell of ...
