The control of transcription in eukaryotes depends on the binding of activators to DNA control  elements. The number of nucleotide sequences found in control elements is surprisingly small: about a  dozen. On average, each enhancer is composed of about ten control elements, each of which can bind  to only one or two specific transcription factors. The particular  combination  of control elements in an enhancer may be more important than the  presence of a single unique control element in regulating transcription of the gene. Even with only a dozen control element sequences, a large number of combinations are  possible. A particular combination of control elements is able to activate transcription only when the  appropriate activator proteins are present, such as at a precise time during development or in a particular cell type.
