QUESTION You are studying a set of mouse genes whose expression increases when cells are exposed to the hormone cortisol, and you believe that the same cortiso-responsive transcriptional activator regulates all of these genes. Which of the following statements below should be true if your hypothesis is correct? The cortisol responsive genes share a DNA sequence in their repulatory regions that binds the cortisol responsive The cortisol-responsne genes must all be an operoo. The cortisol-responsive genes never respond to activators The regulatory regions of the cortisol- esponsive genes must be idn be identa QUESTION Which of the Sollowing is not involved in pout-transcriptiosal control the splaceosomr Mediator proteins cck Sore and Submit to save and submClick Suve Ar Answers to sour oit amwersExplanation / Answer
7. Option A is correct.
Transfer RNA, micro RNA, and ribosomal RNAs do not code for proteins.
8. Option A is correct.
Operons are rare in eukaryotes. A set of genes involved in a common pathway can be regulated by a single regulatory protein if they all contain the same cis-element.
9. Option B is correct.
Mediator proteins are not involved in posttranscriptional control.
