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

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 ...

ONE of the unifying features of life on Earth is that cells almost always use the same genetic language to turn the information in DNA into RNA, then proteins. In a bacterium, a pea or a whale, the ...

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 ...

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 ...

Genes are the building blocks of life, and the genetic code provides the instructions for the complex processes that make organisms function. But how and why did it come to be the way it is? "We find ...

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 ...

A team from the University of Illinois has uncovered surprising evolutionary links between the genetic code and tiny protein fragments called dipeptides. By analyzing billions of dipeptide sequences ...
