Which of the following statements about prokaryotic RNA polymerases is correct? Group of answer choices They require primers to initiate transcription. RNA polymerase uses the coding strand as template to make mRNA. They transcribe both introns and exons Primase is not needed in prokaryotes. They need to bind to nucleotide sequences on DNA known as promoter regions before DNA can be transcribed.

5. (4 points) Find the critical numbers of the function $f'(x) = \frac{x^2 + 81}{x}$. (a) 0 (b) -9, 9 (c) -9, 0 (d) 0, 9 (e) -9, 0, 9 Answer (write the correct letter): 6. (8 points) Consider $f(x) = 15x^2 + x^3$. Find the absolute maximum and absolute minimum values of $f$ in the interval $[-1, 1]$. Work must be shown to receive full credit. Absolute Maximum = occurs at $x = $ Absolute Minimum = occurs at $x = $ 7. (Bonus) Given that $f'(x) = 2(x - 4)(x + 3)$, is the function $f(x)$ increasing or decreasing at $x = 3$? Is the function $f(x)$ concave up or concave down at $x = 3$? Work must be shown to receive credit. Answer:
