Which of the statements about transcriptional activator proteins is INCORRECT? The activator may or may not directly interact with the basal transcription apparatus. They stimulate and stabilize the basal transcription apparatus at the core promoter. They bind to the sugar phosphate backbone as they do not require specific consensus base sequence to bind to the DNA. Some activators are known to have acetyltransferase activity that can alter chromatin structure.

Exercise 3: In the adjacent figure: The points E, K and F are collinear. P is a point on [EG] such that $\frac{EP}{EG} = \frac{\sqrt{2}}{3}$. $EF = \frac{3-\frac{2}{7}}{\frac{2}{7}-\frac{1}{3}} \times (-\frac{19}{9})^{-1}$ and $EK = \frac{3\sqrt{2}}{\sqrt{2}+1} - (2-\sqrt{2})^2$ 1) Show, showing steps of calculation, that $EF = 3$ and $EK = \sqrt{2}$. 2) Prove that (KP) and (FG) are parallel.
