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 ...

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 ...

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 ...

The genetic code is a set of instructions that direct the translation of DNA into 20 amino acids, the basic units of proteins in living cells. The genetic code is made up of codons, which are ...

Scientists at USC have definitively demonstrated that large sets of variations in the genetic code that do not individually appear to have much effect can collectively produce significant changes in ...

Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of much scientific ...

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? A recent ...

The stability, location and translation of mRNAs are regulated through protein interactions and by short and long noncoding interfering RNAs. In this sense, a very significant advance has been ...

The DNA inside of living organisms is packed with information, so much so that it's hard to search genetic databases, but ...

While most of us tend to carry the same general set of genes, within the billions of bases that make up the human genome, there is variation in the sequence from one person to another. Small ...
