Answer:

Serhud [2]

Secondly, the elongation step. A piece of RNA binds to the DNA strand and also an enzyme known as DNA polymeraseIII binds to the piece of RNA (primer). This binding leads to the addition of newer base pairs to the strands thereby elongating it.

Then the termination step, once the strands are formed, those RNA primers are removed from the strand by the action of an enzyme called exonuclase and are being replaces by the appropriate bases.
