Which of the following statements regarding RNA polymerase is FALSE? Group of answer choices RNA polymerase catalyzes the formation of the phosphodiester bonds that make up the sugar-phosphate backbone of an RNA molecule. RNA polymerase catalyzes the addition of a new nucleotide at a 3′-OH. RNA polymerase requires the use of a primer to start a RNA strand. RNA polymerase tends to make more mistakes then DNA polymerases. RNA polymerase moves stepwise along DNA, unwinding the DNA helix to continue complementary base pairing.

Answer

• RNA polymerase requires the use of a primer to start a RNA strand.
  Explanation:
  An enzyme called polymerases catalyzes the formation of phosphodiester bonds. phosphodiester bonds connects the phosphate groups to the pentose sugar. RNA polymerase adds RNA nucleotides on 3′ end of the growing strand. It is DNA polymerase that requires a primer for synthesis to begin, on the other hand, RNA polymerase can initiate synthesis of RNA without a primer. RNA polymerases make more mistakes than DNA polymerases. RNA polymerase moves step-wise along DNA unzipping the double helix to expose the new region of the template strand.
