It is well known that codon bias and gene expression are correlated ... Now, however, Plotkin and colleagues show that it is mRNA structure not CAI that affects expression levels.

The discovery of the double helical structure of DNA by James Watson ... leading to the first deciphering of a codon (UUU for ...

They showed that the RNA sequence UUU specifically coded for the amino acid phenylalanine ... code and fully described each three-letter codon and its corresponding amino acid.
