In most cells, the three - base
sequence uracil - adenine - guanine is a stop signal that shuts down protein production.

The gold - standard method for detecting DNA methylation, which Clark's group developed more than 15 years ago, is bisulphite
sequencing, in which unmethylated versions of the base cytosine are chemically converted into another base,
uracil.
These RNA - binding proteins include
sequences of amino acids that bind to one of the ribonucleotide bases or «letters» that make up RNA
sequences — adenine (A), thymine (T),
uracil (U), and guanine (G).
Thus,
uracil is appropriate for RNA, where quantity is important but lifespan is not, whereas thymine is appropriate for DNA where maintaining
sequence with high fidelity is more critical.
The system also allowed him to determine that a
sequence of three
uracil bases in a row coded for the amino acid phenylalanine.
