The DNA polymerase adds how many nucleotides to the end?
Correct answer: B. 3
- A. 2
- B. 3
- C. 4
- D. 5
Explanation
During elongation, an enzyme called DNA polymerase adds DNA nucleotides to the 3' end of the template. Because DNA polymerase can only add new nucleotides at the end of a backbone, a primer sequence, which provides this starting point, is added with complementary RNA nucleotides.
