DNA double helix measurements

Researchers at the National Physical Laboratory (NPL) and the London Centre for Nanotechnology (LCN) have determined the structure of DNA from measurements on a single molecule using atomic force microscopy (AFM), and found ...

Rapid and accurate mRNA detection in plant tissues

Gene expression is the process whereby the genetic information of DNA is used to manufacture functional products, such as proteins, which have numerous different functions in living organisms. Messenger RNA (mRNA) serves ...

New functions for 'junk' DNA?

DNA is the molecule that encodes the genetic instructions enabling a cell to produce the thousands of proteins it typically needs. The linear sequence of the A, T, C, and G bases in what is called coding DNA determines the ...

Nanopores light up for reading out DNA

Nanopores are ideally suited for threading DNA molecules through them, enabling the genetic code to be read out. Researchers from TU Delft want to make this technology even more powerful by equipping the pores with 'plasmonics'. ...

Unique method creates correct mirror image of molecule

Many molecules have a right and a left form, just like shoes. In pharmaceuticals, it is important that the correct form of the molecule is used. Researchers at the University of Gothenburg, Sweden, have been able to produce ...

The many faces of the bacterial defense system

Even bacteria have a kind of "immune system" they use to defend themselves against unwanted intruders – in their case, viruses. Scientists at the Helmholtz Center for Infection Research (HZI) in Braunschweig, Germany, were ...
