Chemists at the National University of Singapore (NUS) have found a new use for deoxyribonucleic acid (DNA), not just as genetic material, but as a tool for more efficient production of medicinal ...

Scientists found that DNA’s phosphate groups can direct chemical reactions to make the correct mirror-image form of drug molecules. This breakthrough simplifies chiral drug production, reducing waste ...

There are four bases: Adenine and Guanine (purines); Cytosine and Thymine (Pyrimidines). Purines have two carbon-nitrogen rings while pyrimidines have a single carbon-nitrogen ring. Thus, there are ...
