What is the role of RNA polymerase in transcription?
A) It catalyzes the synthesis of a new mRNA molecule.
B) It copies the sequence of nucleotides on the template strand of DNA as a complementary sequence of mRNA bases.
C) It catalyzes the formation of phosphate ester bonds.
D) It is an enzyme.
E) All of the above are roles of RNA polymerase in transcription.

Question

Quizplus · Accepted Answer

RNA polymerase is responsible for catalyzing the synthesis of mRNA by copying the sequence of nucleotides from the DNA template strand into a complementary mRNA sequence and forming the necessary phosphate ester bonds between nucleotides. It is indeed an enzyme that plays a central role in the process of transcription.
