Question: what are the three differences between dna polymerase and rna polymerase?
Answer: The DNA polymerase adds dATP, dGTP, dCTP and dTTP to the growing DNA strand while the RNA polymerase inserts dATP, dGTP, dCTP and dUTP to the growing RNA strand. (Because instead of thymine, the RNA contains uracil). Though the function of both polymerases is to synthesise nucleic acid, both are functionally different.
