Question

Which of the following is the enzyme that replaces the RNA nucleotides in a primer with DNA nucleotides?

a) DNA helicase
b) DNA polymerase
c) RNA polymerase
d) DNA ligase

Answer 1

DNA polymerase is the enzyme that replaces the RNA nucleotides in a primer with DNA nucleotides.

Step-by-step explanation:

The enzyme that replaces the RNA nucleotides in a primer with DNA nucleotides is DNA polymerase. DNA polymerase is responsible for synthesizing a new DNA strand by adding complementary nucleotides to the existing template strand. In this case, it replaces the RNA nucleotides in the primer with DNA nucleotides to form a complete DNA strand.
