DNA primase activity
Catalysis of the synthesis of a short RNA primer on a DNA template, providing a free 3'-OH that can be extended by DNA-directed DNA polymerases. Catalyzed by a DNA-directed RNA polymerase that forms a complex with alpha DNA polymerase.
DNA replication, synthesis of RNA primer
The synthesis of a short RNA polymer, usually 4-15 nucleotides long, using one strand of unwound DNA as a template; the RNA then serves as a primer from which DNA polymerases extend synthesis.
