It's DNA, but not as we know it. In a world first, Australian researchers have identified a new DNA structure—called the i-motif—inside cells. A twisted 'knot' of DNA, the i-motif has never before been directly seen inside ...

Not only can synthetic molecules mimic the structures of their biological models, they can also take on their functions and may even successfully compete with them, as an artificial DNA sequence designed by Ludwig-Maximilians-Universitaet ...

If you had to copy billions of letters from one sheet of paper to another, you'd probably make a few mistakes. So it might not come as a surprise that when DNA makes a copy of its three-billion-base genetic code, it can slip ...

Life would be impossible if the DNA in dividing cells were replicated with anything less than near-perfect precision. Every time a nucleated cell commits to becoming two cells, every "letter" of its genome must be replicated ...
