In the follow-up work to the experiment shown in Figure 19.6, the researchers used a technique that allowed them to see if two DNA sequences are in close physical proximity (association). They applied this method to examine how often an enhancer and the core promoter of the Hnf4a regulatory gene were near each other. A logical prediction is that compared with rats born to mothers fed a healthy diet, the Hnf4a gene in rats born to mothers fed a protein-poor diet would a. show no difference in how often the promoter and enhancer associated. b. never show any promoter–enhancer association. c. show a lower frequency of promoter–enhancer association. d. show a higher frequency of promoter–enhancer association.

Accepted Answer

Hello everyone here. We have a question asking which one is the incorrect statement regarding transcription control. So we have a enhancers are short nucleotide sequences that increase the transcription rate in the genome. This is true enhancers are short nucleotide sequences that either bind upstream or downstream of genes and they do this to enhance their transcription in the genome. So is correct. Be enhancers act on the promoter region itself. This is untrue. The enhancers don't bind on the promoter itself, but they grind with the activator protein, so B is incorrect. See promoters are long nucleotide sequences that initiate transcription. This is correct. The repressors are D. N. A. Or RNA binding proteins that inhibit the transcription of genes. This is correct. So our answer is B enhancers act on the promoter region itself. Thank you for watching. Bye.
