The RNA primer synthesized by primase to initiate phage G4 DNA replication
Abstract
With phage G4 DNA as template, primase (the dnaG protein) synthesizes a 26- to 29-residue RNA transcript at the origin of replication. The sequence starts with ATP and contains a hairpin region of one A-U and seven G-C base pairs. Covalent linkage between the RNA and the newly synthesized complementary DNA chain indicates that the RNA transcript serves as a primer.
