... Between genes there is DNA, mostly of unknown function. The size and nature of this DNA vary with the genome. In bacteria and fungi there is little, but in mammals the intergenic regions can be huge. Sequences of DNA that exist quite distant from a given gene can affect the regulation of that gene. ...
