here are the regulatory regions of genes encoding Y and ΔY (top). You have cells which express the steroid hormone (X) receptor (Xrec) under the control of a constitutive promoter. Hormone-bound Xrec is a transcription activator binding to its recognition sequence XrecBS. The transcription factor Y contains a DNA-binding domain at the amino terminus that recognizes the sequence YBS and a c-terminus polyglutamine sequence. The transcription factor ΔY is the same as Y, but is missing the c-terminus polyglutamine sequence. The relative half-lives of X, Y, and ΔY are as follows t½X = 5, t½Y = 5, t½ΔY = 15. Which of the graphs best describes the rate of transcription from the Y promoter after the addition of hormone X at the time indicated? Select one:
