When the replication fork is moving towards DNA double strand in the direction 5'- 3', a "Single-strand Binding Protein" (or SSB) -a dnaB gene product- must be removed in order to allow DNA polymerase to add the following nucleotide.
DNA Polymerase III adds nucleotides during DNA replication. DNA Polymerase I also adds nucleotides (to a lesser extent). DNA Pol I is responsible for replacing the primers with dNTPs, these sections are then joined to the rest by DNA Ligase.
DNA Polymerase is the enzyme which adds new nucleotides during replication.

RNA Polymerase
Basically, RNA polymerase's role is very similar to that of DNA polymerase. RNA polymerase is an enzyme that is used during transcription in the nucleus. Similar to DNA polymerase, RNA polymerase codes for the complementary nucleotides to a DNA strand. Instead of thymine though, uracil codes with adenine. This coded mRNA strand then travels from the nucleus to the ribsome where translation occurs - the result is protein made from an amino acid chain. To answer your main question - RNA polyermase adds the complementary nucleotides to the DNA strand using uracil instead of thymine. hope that helps :)

DNA and RNA polymerase
DNA Polymerases DNA Polymerases
The enzyme that adds nuclleotides to exposed nitrogen bases is DNA polymerase. This is how DNA can be replicated or repeated in the cell cycle.
RNA polymerase is the enzyme that adds and links complementary RNA nucleotides during transcription
DNA Polymerase I
DNA polymerase 1,2,3 are enzymes involved in adding nucleotides during replication
RNA Polymerase
More than two enzymes are involved. However, the main ones are DNA Polymerase I and DNA Polymerase III. DNA Polymerase III adds new nucleotides and DNA Polymerase I removes primers.
