What statement(s) below best describe coordinate control of genes in eukaryotic cells?

i. genes involved in a related metabolic process are scattered over different chromosomes, but their coactivation is achieved because they share a specific combination of control elements that bind to the same activator molecules.

ii. different genes that code for proteins involved in the same metabolic process share the same enhancer regions.

iii. the coordinated expression of different genes involved in the same metabolic process is enhanced by the bending of dna to bring the bound activators closer to the promoter to form a transcription factory.
