Select the statements about RNA polymerase that are true. Multiple select question.

A. Eventually, the mRNA is released, and the RNA polymerase detaches from the DNA.

B. RNA polymerase is an enzyme that regulates RNA synthesis, binding to a specific section where an mRNA will be synthesized.

C. As a DNA strand unwinds, the RNA polymerase initiates mRNA synthesis and moves along one of the DNA strands in the 3' to 5' direction.

D. A strand of DNA that is read by RNA polymerase is called the template strand, and mRNA is synthesized as a complement to the DNA nucleotides.

E. On the nontemplate strand of DNA, the mRNA transcript is manufactured in a 3' to 5' direction, adding each new RNA nucleotide to the 5' end.
