Cells working with an expanded genetic code could make more diverse medicines. A new study shows scientists are within striking distance. One of modern biologists' most ambitious goals is to learn how ...

Superimposed on the genetic sequences coding for amino acids is a second genetic code. This second genetic code, which makes use of dual-use codons, or duons, specifies how genes are controlled. The ...

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 ...

Represented here by a tomato and a rope, ribosomes are central to all life on Earth because they help translate genetic information into proteins. Image by Gene-Wei Li/UCSF A hidden and never before ...

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 ...

A hidden and never before recognized layer of information in the genetic code has been uncovered by a team of scientists, thanks to a new technique called ribosome profiling, which enables the ...

The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 ...

LA JOLLA, CA—One of modern biologists’ most ambitious goals is to learn how to expand or otherwise modify the genetic code of life on Earth, in order to make new, artificial life forms. Part of the ...
