Caltech researchers have identified a novel chemical reaction that could explain the formation of the building blocks of DNA ...

In Biology 101, we learn that RNA is a single, ribbon-like strand of base pairs that is copied from our DNA and then read like a recipe to build a protein. But there's more to the story. Some RNA ...

RNA therapeutics have emerged as one of the most promising new classes of medicines. Eight small interfering RNA (siRNA) ...

When RNA molecules are synthesized by cells — a critical process in the creation of proteins and other cellular functions — they typically undergo a series of “folding” events that determine their ...

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot. These knots can play ...

Ribonucleic acid (RNA) molecules may be best known for their job ferrying the genetic information encoded in DNA to a cell's protein factories, but these molecules aren't just a middleman for protein ...

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint for these cells is essentially the same. Where do those differences come ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...
