Primossome

Primosome is a protein complex that creates RNA primers during DNA replication. This complex is formed by seven proteins: DnaG primase, DnaB helicase, DnaC helicase, DnaT, Pri A, Pri B and Pri C. During de DNA replication, the primossome is used, in the replication fork, once in the leading stand and multiplied times in the lagging strand, one for each Okazaki fragment.
