A researcher is trying to identify regulatory DNA sequences near a gene of interest. Several modified versions of the gene have been made and tested to detemine their levels of transcription: highly transcribed (+++); moderate transcription (++); and very little transcription (+). Deleted portions of the gene and surrounding DNA sequence are indicated by dashed lines (A, B, and C). Exons are indicated by boxes. +1 +++ B ++ Which sequence above normally acts as an enhancer for this gene? O A. A О в. В O C. C O D. None of the sequences funtion as an enhancer E. All of the sequences (A, B and C) function as enhancers.
