Answer the following question given this paragraph: 

Figure 16.9 An enhancer is a DNA sequence that promotes transcription. Each enhancer is made up of short DNA sequences called distal control elements. Activators bound to the distal control elements interact with mediator proteins and transcription factors. Two different genes may have the same promoter but different distal control elements, enabling differential gene expression.


Q: Each enhancer is made up of short dna sequences called what?


A:
distal control elements
