E) Both B and C are correct.

Quizplus · Accepted Answer

Choice A is incorrect as the rho subunit is involved in termination of transcription, not initiation. Choice B is correct as RNA polymerase reads the DNA template strand in the 3' to 5' direction and synthesizes the complementary RNA strand in the 5' to 3' direction. Choice C is also correct as the first nucleotides placed in an RNA transcript of prokaryotic cells are GTP and ATP. Therefore, E is the correct answer.
