複選題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.
