In early evolution, the duplication of genes is an important event that resulted in new genes and genetically novel organisms.  For instance, a small soluble iron-sulfur protein known as ferredoxin is found in both modern and ancient entities. Indeed, this commonplace molecule is responsible for mediating electron transfer in a range of metabolic reactions. Ancient protein fuels modern cells Now, a study led by researchers … Continue reading Researchers insert a synthetic primordial protein into a living organism.
