What is the function of the RNA primer in DNA replication?

During DNA replication, RNA primase puts an RNA primer in the lagging strand. What is the function of this RNA primer? Why can't the enzymes put DNA fragments directly?

Kalee R.

RNA primase is needed because the enzymes that synthesize DNA can only attach nucleotides to an existing strand of nucleotides.
