Practice questions

1 of 50Practice questions for this set

A team uses an in vitro transcription system with purified RNA polymerase II and general transcription factors to transcribe a DNA template encoding a stress-response enzyme. They add either (i) all four rNTPs, (ii) all four dNTPs, or (iii) all four rNTPs plus an RNase that degrades single-stranded RNA. Which condition is expected to yield the highest amount of full-length RNA transcript?
