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 relied on one central assumption: the genetic code is precise. DNA is transcribed into RNA, RNA is translated into proteins, and each three-letter codon has a fixed meaning.
Methane-producing archaea from the species Methanosarcina acetivorans. The microbes are stained with a fluorescent dye that specifically binds to the membranes of archaea. The beauty of the DNA code ...
