Answer:
Primase is a DNA dependent RNA polymerase. It adds RNA primer to the DNA strand and lay the foundation of DNA replication.
It is important because DNA polymerase can add nucleotides to the 3'- end of the strand.
Primase, in the form of RNA primers provide free 3'- end to the DNA polymerase and thus, help in initiating DNA replication.
At the end of replication RNA primers are removed by DNA polymerase I.
