Title: What is the Primer that is needed to initiate the synthesis of a new DNA strand?

Is it ligase?

DNA Primase  ;) (an RNA Pol).

Is it ligase?

Ligase is the enzyme that 'sews' up the backbone when the primers are replaced with DNA.

EDIT: Just read the question properly and they are probably just after 'RNA'
(DNA Primase is the enzyme that synthesises these strands)

I'm not sure now....
My choices are:
RNA
DNA
Protein
Ligase
Primase

So would it be RNA, or Primase?

I think RNA is right.
