The Gene for a Hormone Necessary for Insect Development Contains

question 38

Short Answer

The gene for a hormone necessary for insect development contains binding sites for three transcription regulators called A, B, and C. Because the binding sites for A and B overlap, A and B cannot bind simultaneously. You make mutations in the binding sites for each of the proteins and measure hormone production in cells that contain equal amounts of the A, B, and C proteins. Figure 8-52 summarizes your results. In each of the following sentences, fill in the blank one of the phrases within square brackets to make the statement consistent with the results.

-Protein A is a __________ [stronger/weaker] activator of transcription than protein B.
