A new study finds that at least one Archaea has surprisingly flexibility when interpreting genetic code, which goes against a ...

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 ...

61 codons specify one of the 20 amino acids that make up proteins 3 codons are stop codons, which signal the termination of protein synthesis Importantly, the genetic code is nearly universal, shared ...

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 ...

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 ...

For decades, biology has relied on one central assumption: the genetic code is precise. DNA is transcribed into RNA, RNA is ...

It's a dogma taught in every introductory biology class: Proteins are composed of combinations of 20 different amino acids, arranged into diverse sequences like words. But researchers trying to ...

Today, thousands of databases with biological data are publicly available. They include data on gene and protein sequences and detailed measurements of different cellular parameters, such as the exact ...

The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that's added to a chain of amino acids ...
