At some point during the evolution of life on Earth, inorganic matter became organic, nonliving matter became living. How ...

Amino acids play a fundamental role in regulating how cells respond to drugs. These molecules, which form proteins, act like ...

DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

Credit: Kateryna Kon/Science Photo Library/ What is DNA, and how does it work? You don't need a degree in genetics to understand. Here, we'll give an overview of DNA and answer questions ...

However, the research leading to the discovery of nucleic acid structure started several years previously and involved many different researchers across the world.

Co-polymerization of glycol nucleic acid monomers with dicarboxylic acids in simulated early Earth drying environments readily gives rise to plausible prebiotic xeno nucleic acid co-polymers ...
