Eukaryote Genome Regulation     All organisms Must regulate which genes are expressed at any  given time   During development of a multicellular organism Its cells undergo a process of specialization in form  and function  called  cell differentiation     Gene expression can be regulated at any  stage, but the  key step is transcription

  Each cell of a multicellular eukaryote — Expresses only a fraction of its genes   In each type of differentiated cell —A common set of "housekeeping" genes is  expressed —A unique subset of genes is expressed      (codes for proteins unique to cell function) How does this selective expression of  specific genes occur?
