help me please

The proteins from three cell types from the same organism treated with a radioactive probe. The cell extract was mixed w results? re extracted. In addition the entire control region (promoter plus enhancers etc) for a gene was isolated and ith the DNA and subjected to an electrophoretic mobility shift assay. Which of the following are true of these Remember to think of all types of control elements (enhancers, silencers, promoters Assume the transcription factors are the same size (not usually true, but for this question) Cell type None 1 2 3 cell type 2 has the highest expression cell type 3 definitely has the lowest expression. The DNA in cell type 2 is larger All three cell types are regulating (up or down) the transcription of this pene. Cell t 2 likely has more transcription factors bound
