Primase

Explanation:

Primase is a form of RNA polymerase enzyme that is involved in DNA replication which catalyses the production of small segment of DNA or RNA called primer complimentary to a short stranded DNA template.

The RNA molecule is later removed by 5' to 3' exonuclease and the DNA later filled it and occupy the position.
