Enhancers range from 200 bp to 1 kb in length and can be either proximal, 5’ upstream to the promoter or within the first intron of the regulated gene, or distal, in introns of neighboring genes or intergenic regions far away from the locus.
Pojačivači se kreću od 200 bp do 1 kb u dužini i mogu biti ili proksimalni, 5' do promotera ili unutar prvog introna regulisanog gena, ili distalni, u intronima susednih gena ili intergenskih regiona daleko od lokusa.
