[e] the activity of an existing protein can be increased or decreased [a] grouping genes into operons allows a set of genes to be expressed together [b] genes with related functions are are not grouped together, but have similar regulatory regions and can be expressed simultaneously [c] regulatory proteins can control whether or not a gene is transcribed to mRNA [d] spliceosomes can carry out alternate splicing to produce different mRNA molecules from a given gene
