Comparing DNA sequences in different species indicates that more DNA segments that do not code for protein have been conserved (unchanged) than protein- coding regions. These non-protein-coding regions areinterpreted as gene regulatory elements. Suggest why gene regulatory elements have not undergone many changes during the course of evolution.
