However, while scientists have established that these regulatory sequences have important functions, they do not know what function each sequence performs, nor do they know which gene each one affects ...

it has been shown to have vital physiological functions. Scientists have now developed new high-precision tools able to identify what these noncoding sequences do. The study may eventually ...

The rule was that DNA transcribed into messenger RNA, which translates into proteins essential for biological functions with the core principle that only a small number of three-letter sequences ...

The team of researchers created genetic sequences never before seen in nature ... "What we have here are molecular machines that function quite well within a living organism even though they ...

The change in function (or phenotype ... where several conserved sequences of amino acids (motifs), such as the Walker A and B motifs, Q- and H-loops, and the C-motif have been retained.

The research appeared online January 4 in the journal Public Library of Science ONE in a paper titled “De Novo Designed Proteins from a Library of Artificial Sequences Function in Escherichia ...
