Multiple choice

Which of the following is NOT a role of RNA Polymerase?

  2. Unwind the DNA double helix

  3. Create covalent bonds between RNA nucleotides

  4. Add complimentary RNA nucleotides to DNA with hydrogen bonds

A Correct answer
Explanation

RNA polymerase does not synthesize or create individual RNA nucleotides from scratch; these free nucleotides are already present in the nucleoplasm. Instead, RNA polymerase unwinds DNA, aligns complementary RNA nucleotides, and catalyzes the formation of covalent phosphodiester bonds to link them into an mRNA strand.
