Our DNA is constantly under threat — from cell division errors to external factors like sunlight and smoking. Fortunately, ...

But real lightning would have struck infrequently—and mostly in open ocean, where organic compounds would have quickly ...

What have we learned about RNA structure and function so far? Although RNA is a single-stranded molecule, researchers soon discovered that it can form double-stranded structures, which are ...

The end of the RNA strand remains water-free and can spontaneously re-form new RNA bonds. Braun's laboratory demonstrated ...

This requires RNA strands to become double-stranded before separating. Although there are many other questions about how this ...

Researchers at Case Western Reserve University have discovered molecules that present the potential to drive the development ...

The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA ... the entire sequence pairs with the target strand with high complementarity. This often results ...

DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific ...
