_ enzyme needs a primer for the initiation of its function
Correct answer: B. DNA polymerase
- A. RNA polymerase
- B. DNA polymerase
- C. Primase
- D. Ligase
Explanation
The synthesis of a primer is necessary because DNA polymerases, can only attach new DNA nucleotides to an existing strand of nucleotides. The primer therefore serves to prime and lay a foundation for DNA synthesis.
