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 ...

Human genes are written in long strings of three-letter units composed of four different nucleotides. These units—or ...

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 ...

Transcription and translation are processes a cell uses to make all proteins the body needs to function from information stored in the sequence of bases in DNA. The four bases (C, A, T/U, and G in the ...

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 ...

During protein synthesis, the genetic information stored in DNA is first transcribed into mRNA. The mRNA then travels to the ribosome, where translation occurs. Here's how anticodons facilitate the ...

DNA is admired for its perfection as a programmable information molecule: it uses repeating polymerization chemistry to link four nucleotide building blocks (adenine, cytosine, guanine, and thymine) ...

Proteins are built by mixing and matching amino acids, but researchers want to create new functions by adding noncanonical amino acids (ncAAs). However, this process often requires complex whole ...
