Clues to the genetic code’s origin may be hidden in tiny protein fragments, revealing a synchronized and highly structured path to life’s earliest molecular systems.

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 ...

Not all parts of our genetic code are equal, even when they appear to say the same thing. Scientists have discovered that ...

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 ...

Jim Maher and his colleagues are like a hinge in the complex world of scientific research. Their work, and that of others toiling behind-the-scenes at the basic-research level, is folding more ...

It was long thought that unless a mutation in a gene's sequence changed the resulting amino acid, it had no significance - the mutation was said to be 'silent.' But researchers have been questioning ...

There are few hard and fast rules in the study of life, but perhaps the closest we get is the central dogma of molecular biology: DNA is transcribed to RNA, which gets translated into proteins. The ...

Synthetic biologists from Yale were able to re-write the genetic code of an organism - a novel genomically recoded organism (GRO) with one stop codon - using a cellular platform that they developed ...

Life runs on instructions you never see. Every cell reads DNA, turns that message into RNA, and then builds proteins that keep you alive. That translation system feels so basic that it is easy to ...
