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.

How does the cell convert DNA into working proteins? The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA. But ...

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

ITHACA, N.Y. -- The process by which a cell reads the genetic code in its DNA in order to manufacture a protein is complex, involving dozens of enzymes and other biological molecules working together.

DNA repair proteins act like the body's editors, constantly finding and reversing damage to our genetic code. Researchers have long struggled to understand how cancer cells hijack one of these ...

Proteins are like Spider-Man in the multiverse. The underlying story is the same: each building block of a protein is based on a three-letter DNA code. However, change one letter, and the same protein ...
