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 ...

Starting from the four innermost letters and working to the outermost ring, this table shows shows which three-letter base sequence or codon encodes which amino acid. In the journal Angewandte Chemie ...

Scientists trying to engineer biologic molecules with new functions have long felt limited by the 20 amino-acid building blocks. Researchers are working to develop ways of putting new building ...

Amino acids are the building blocks of protein. These molecules come together to form proteins. Your body uses them for many important functions, such as making hormones, building muscle, and ...

Living organisms synthesize a staggering variety of proteins by combining 20 amino acids into chains of any length and order. In the past, to expand protein diversity beyond the scope of these 20 ...
