A newly mapped step in DNA replication suggests that strand separation begins at a precise junction between two helicase rings. Credit: Shutterstock Researchers mapped where DNA first opens and how a ...

The genetic code acts as life's instruction manual, telling cells how to build proteins from DNA and RNA. Though it's a marvel of molecular precision, the path it took to evolve remains unclear. Fresh ...

The first great branching of the evolutionary tree, between bacteria and archaea, may have happened before either of them ...

Blue chromosome DNA and gradually glowing flicker light matter chemical when camera moving closeup. Medical and Heredity genetic health concept. Technology science. 3D illustration rendering “Today, ...

Did you know one of the largest collections of marine DNA in the entire world is hiding just outside D.C.? In today’s episode of “Matt About Town,” we’re taking an even deeper dive into the ...

The DNA of nearly all life on Earth contains many redundancies, and scientists have long wondered whether these redundancies served a purpose or if they were just leftovers from evolutionary processes ...

Nearly all living organisms use the same genetic code, a complicated mechanism by which genetic information is translated into proteins, the building blocks of life. A new study suggests conventional ...

Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of much scientific ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...

Decades of research has viewed DNA as a sequence-based instruction manual; yet every cell in the body shares the same genes – so where is the language that writes the memory of cell identities?

While the central dogma of molecular biology outlines the linear flow of genetic information from DNA to RNA to proteins (black lines), glycomics introduces a “3rd code of life”—glycans—that operates ...
