16. RNA polymerases synthesize a new strand of nucleic acid that is complementary to one of the chromosomal DNA strands. Which of the following statements regarding RNA POLYMERASE is CORRECT?
(A) RNA polymerases synthesize a strand of ribonucleotides.
(B) Like DNA polymerase, RNA polymerases initiates transcription with a primer.
(C) Unlike replication, the newly transcribed sequences do not remain base-paired with the template but are displaced after reaching a length of about 10 nucleotides.
(D) Most eukaryotes have three different RNA polymerases, including RNA polymerase I, II, and III.
(E) RNA Polymerase II is responsible for transcription of mRNA.
