primase
A polymerase that acts on a template DNA strand to produce RNA, resulting in the formation of an RNA primer needed in RNA replication. SYN: dnaG. [primer + -ase]

* * *

pri·mase (priґmās) a DNA-directed RNA polymerase that synthesizes an RNA primer complementary to one of the DNA strands in order to initiate DNA synthesis during DNA replication.
