In prokaryotic RNA synthesis
A) the rate of incorporation of nucleotides is constant throughout the elongation process
B) the r (rho) protein is always required for termination
C) a unique series of three bases leads to termination
D) inverted-repeat sequences in the DNA being transcribed can lead to termination

Question

Quizplus · Accepted Answer

Inverted-repeat sequences in the DNA being transcribed can lead to termination in prokaryotic RNA synthesis. Choice A is incorrect because the rate of incorporation of nucleotides can vary during elongation. Choice B is incorrect because not all terminations require the r protein. Choice C is incorrect because a series of three bases (codon) leads to the addition of an amino acid, not termination.
