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 ...

For decades, biology has been organized around a deceptively simple idea: DNA is transcribed into RNA, RNA is translated into ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

Determining protein structures requires crystals, but getting proteins to crystallize has long depended on a slow, unpredictable process of trial and error ...
