Nucleic acids may be labeled at their 3’ end, 5’ end, or throughout the molecule, depending on the desired application. Myriad of enzymatic or chemical methods are utilized to generate nucleic acids ...

Scientists hoping to get a glimpse of molecules that control brain activity have devised a new probe that allows them to image these molecules without using any chemical or radioactive labels.

There is a war going on to win over the hearts and minds of molecular biologists: Radioactive isotopes-long the gold standard for tagging and later detecting RNA and DNA strands- are being challenged ...
