A team from the University of Illinois has uncovered surprising evolutionary links between the genetic code and tiny protein ...

The same amino acid can be encoded by anywhere from one to six different strings of letters in the genetic code. Andrzej Wojcicki/Science Photo Library via Getty Images Nearly all life, from bacteria ...

This circular diagram represents the genetic code, showing how the four nucleotide bases of RNA (adenine [A], cytosine [C], guanine [G], and uracil [U]) form codons that specify amino acids. Each ...

Autosomal DNA tests are a way of looking at the code that exists inside of all of your cells. They reveal a world of genetic information that can be used medically and to discover your ethnic makeup.

Despite awe-inspiring diversity, nearly every lifeform—from bacteria to blue whales—shares the same genetic code. How and ...

Snifflers of the world rejoice: Scientists are one step closer to finding effective treatments for the common cold now that researchers have deciphered the genetic code of the ubiquitous virus. While ...

As wildly diverse as life on Earth is—whether it’s a jaguar hunting down a deer in the Amazon, an orchid vine spiraling around a tree in the Congo, primitive cells growing in boiling hot springs in ...

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 ...

Arrow worms, or chaetognaths, are strange ocean predators that have puzzled scientists for more than a century. They have transparent, torpedo-shaped bodies, sharp grasping spines near their mouths, ...
