When we say a gene is expressing itself, what does "gene expression" mean in relation to protein synthesis?
-Gene expression is the process by which the information encoded in a gene is used to either make RNA molecules that code for proteins or to make non-coding RNA molecules that serve other functions. Gene expression regulates when and where RNA molecules and proteins are made, as well as how much of those substances are made. In connection to protein synthesis, it is those RNA molecules coded for proteins that undergo transcription (DNA into RNA) and eventually translation (RNA to proteins) where they will be coded into amino acids, the basic building blocks needed to form proteins.
