Gene expression is the complex process of producing proteins from a specific gene sequence encoded in DNA. The DNA in the nucleus of a cell is constantly surrounded by the machinery of gene expression. That machinery will attempt to start the process of transcription, the first step of gene expression, for any sequence it bumps into. Recall that every part of a cell is a chemical soup of molecules moving at incredible speeds, interacting with everything that they can possibly interact with, as fast as possible, countless times every second. Control over which genes are expressed at any given time is a matter of the structure of DNA, which sequences are exposed and which are spooled aroun…
