A fragment of DNA with a radioactive label is incubated with DNase in the presence and absence of a protein that acts as a positive regulator of transcription. The samples are then run on a gel and visualized with autoradiography. Which statement describes a possible result and conclusion from such an experiment?
A) The banding pattern on the gel is the same with and without the transcriptional regulator, therefore the protein binds the DNA fragment. B) Some bands on the gel are absent in the sample with the transcriptional regulator, therefore the protein does not bind the DNA fragment. C) Some bands on the gel are absent in the sample with the transcriptional regulator, therefore the protein binds the DNA fragment. D) Some bands on the gel are absent in the sample without the transcriptional regulator, therefore the protein does not bind the DNA fragment.
