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 ImagesNearly all life, from ...

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 ...

Autosomal DNA tests can be helpful for diagnosing particular genetic diseases or predispositions for diseases. A genetic disease involves a particular mutation or sequence in your genetic code.

The findings, which detail how amino acids shaped the genetic code of ancient microorganisms, shed light on the mystery of how life began on Earth. "You see the same amino acids in every organism ...

In a giant feat of genetic engineering, scientists have created bacteria that make proteins in a radically different way than all natural species do.

For example, one of the cornerstones of conventional views of genetic code evolution rests on the famous Urey-Miller experiment of 1952, which attempted to simulate the conditions on early Earth ...
