How does the cell convert DNA into working proteins? The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA. But ...

It has long been accepted that a gene's protein-coding information is contained in only one of its two DNA strands. But in 22 February Nature, Victor Corces and co-workers at the Department of Biology ...

Two forms of the ubiquitous protein actin differ by only four amino acids but are dissimilar in 13% of their nucleotide coding sequences due to silent substitutions. A new study reveals that these ...
