Biology might ultimately provide a solution, however. Researchers have identified bacteria that evolved the ability to digest ...

But real lightning would have struck infrequently—and mostly in open ocean, where organic compounds would have quickly ...

Mitochondrial diseases, arising from mutations in mitochondrial DNA (mtDNA), are a diverse group of disorders that lead to ...

This important study shows, for the first time, the structure and snapshots of the dynamics of the full-length soluble Angiotensin-I converting enzyme dimer. The combination of structural and ...

a modified version of PHA synthase that could polymerize amino acid monomers. These enzymes enabled bacteria to create PEA precursors and link them into polymer chains. Initially, the process was ...

By tweaking the monomer ratio and salt content ... of chemistries available to them through the side chains of their amino acid building blocks, which can confer properties beyond the capability ...

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?

Polymers are made of monomers, and in DNA ... In its structure, DNA contains a pattern for producing amino acids, proteins, lipids, sugars, and every other biomolecule an organism makes.
