The genetic code is the set of rules by which information encoded in genetic material (DNA or RNA sequences) is translated into proteins (amino acid sequences) by living cells. Specifically, the code ...

Rule-breaking organism: Condylostoma magnum treats all three stop codons as amino acid instructions, defying the universal genetic code. Why it matters: The discovery challenges a core molecular ...

Unexpected genetic twist: An Oxford pond organism uses two universal stop codons to code for amino acids instead of ending protein synthesis. Why it matters: The discovery challenges the ...

Quantitative experiments in evolutionary biology have ushered in a new era. Theories can now be tested experimentally, as they are in the physical sciences. Digital organisms (self-replicating ...

Inhibitory GABAergic feedback neurons tune direction-selective motion signals in Drosophila, sharpening behavioral responses to rapidly changing visual stimuli and expanding canonical feedforward ...
