For decades, biology students have learned one rule about the genetic code that supposedly has no exceptions: three specific DNA sequences act as stop signs, telling the cell’s protein-building ...

A microscopic organism from a freshwater pond is playing by a different set of genetic rules. The newly identified protist, Oligohymenophorea sp. PL0344, which scientists stumbled across while ...

The genetic building blocks of life—formed from the four nucleotides adenine (A), cytosine (C), guanine (G), and thymine (T)—are read in groups of three known as codons. While some codons (known as ...

A change in the DNA sequence of a codon may not change the corresponding amino acid residue in the encoded protein because each residue can be encoded by several codons. This is called the Wobble ...

The pond at Oxford University Parks is not much to look at. It is a small, artificial freshwater basin on the edge of campus, the kind of place students walk past on the way to lectures. But in April ...
