Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. How did scientists discover and unlock this amino acid code? Once the budding ...

The genetic code is a set of rules defining how the four-letter code of DNA is translated into the 20-letter code of amino acids, which are the building blocks of proteins. The genetic code is a set ...

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, ...

Scientists at The Scripps Research Institute (TSRI) report in an upcoming article in the Journal of the American Chemical Society their synthesis of a form of the bacterium Escherichia coli with a ...

Students will compare the sequence of amino acids in a gene shared between humans and six other organisms and infer evolutionary relationships among the species. In the NOVA scienceNOW segment Bird ...
