An enzyme complex called RNA polymerase is also known as DNA-dependent RNA polymerase because:
A) DNA codes for the subunits of this protein
B) DNA serves as a template for translation
C) hydrolysis of DNA provides the energy for RNA polymerase
D) DNA serves as a template for transcription
E) DNA is required as a primer for this polymerase

Question

Quizplus · Accepted Answer

RNA polymerase is DNA-dependent because it uses DNA as a template to synthesize RNA molecules during transcription. Therefore, the correct answer is D, "DNA serves as a template for transcription." The other options are not accurate descriptions of why RNA polymerase is DNA-dependent.
